Hi, my intro. And scared and need help.

So first of all hi. I just joined this group (eve) to track periods. So heres a little about me. Please be patient lol. I have 3 healthy(full term) pregnancies/children. Lol. Tyler (9yrs) Caden (7yrs) and Kirsten (4yrs, turns 5 in Dec). My boy's i had easy pregnancies and labor/delivery. My pregnancy with Kirsten was a bit of a challenge. I had pain quite a bit and had preterm labor at 32 weeks that got stopped(thank God) and was put on bedrest and medication because the contractions never really stopped. She made her arrival just after 37 weeks and was perfectly healthy.

We started ttc Dec 2014/ Jan 2015 and got pregnant ( edd was Oct 27). But I had a miscarriage in April and had a d&c on April 30 2015. There was nothing obvious to see for cause. That was hard for my whole family. We lost baby at 12 weeks but didn't find out until 14 weeks. (They called it a 2nd trimester loss) then we decided to ttc again. And got pregnant in August (edd was June 4) and we had another devastating miscarriage in Dec. I had another d&c Dec 2015. Another normal fetus. So we tested thyroid and was a little abnormal so we started medication to bring it to normal. With the hopeful thought that was why I was having miscarriages. So we decided to ttc again remaining hopeful that things would be great. We got pregnant again in April or May(i can't remember) (edd was Jan 27 2017) and to our surprise we had another miscarriage in July and suffered through another d&c July 13 2016. Another normal fetus. So at this point we are completely devastated and lost. We couldn't figure out a reason for my losses considering we had healthy children. Nothing made sense. All miscarriages happened around the 12/13 week period and all 3 had nothing wrong. So we went to a fetal maternal medicine doctor to run some possible tests. Well there were only 3 tests they could think to run because of my situation. Well 2 of the 3 tests weren't covered by insurance so I couldn't do those. One was a genetic test on me (but wasn't likely since I had children) and the other was to check if there was something wrong with my cervix or something like that. Those 2 weren't covered. And then one for my blood to see if it was clotting or something. We did that one and it was normal. So i decided to wait a little while to try tracking my periods and ovulation(because i heard sometimes that can cause miscarriages). And i was planning on starting to take prenatal vitamins to get the stuff they have before getting pregnant. I was planning on waiting at least until early next year to start ttc again (for the last attempt). Well here we are in October and af is due now (I'm officially 1 day late) and my nipples have been tingly ( usually my boobs hurt for ovulation and af, not my nipples) and I have been having constant headaches, usually only a couple headache a week. And last night I was getting really dizzy. I took a hpt on Monday and it was negative, but I'm not sure how accurate it was (it was a $.88 Walmart test and fmu was quite clear). So now it's very early Sunday morning and I am planning on getting another test to take Monday(if af doesn't show up). Also i had some clear cm with a tiny tinge/streak of brown about a week or 2 ago. Then Friday or Saturday I was try to check cervix(not sure I have that figured out) and there was a creamy cm when I checked my finger. And when I was looking online for checking cervix there was some pictures of this same cm in a picture for an early pregnancy cervix. So I am trying not to freak out because we weren't trying and using condoms. We have planned all of our pregnancies and so if I am now pregnant then this is completely unexpected and I am scared because it's only like 2/3 months after my last miscarriage and d&c. And of course the whole reason for having miscarriages we are still clueless about. So I am pretty sure we will loose it if we were pregnant. But I haven't ever had an early miscarriage, all were in 2nd trimester. I honestly am afraid. We weren't trying we were preventing and now I have a feeling that I am pregnant, i just need to get a test to confirm. At this point I am afraid I am only able to pray for things to be ok, but that hasn't helped me so far. So I just want to cry.

Can anyone who has suffered through miscarriages and had gone on to have their rainbow baby tell me if you made any changes to help you have a successful pregnancy? Like changed diet, meditation/relaxation, vitamins, etc? My husband and I have decided that if we loose a 4th baby that we can't handle it mentally, emotionally or physically(on my part). Therefore if we miscarry again I am discussing permanent birth control to make sure I don't get pregnant again. I obviously don't have a problem getting pregnant, I have a problem keeping the pregnancy. Oh and by the way I am 31 and my husband and I just celebrated our 8th anniversary but we been together for 10 years. So ya. Sorry for the novel. I just wanted to introduce myself and a little history as to why I'm afraid. Lol. Hopefully someone in here can give a little advice and hopefully some support. Thanks everyone.
