Hi ladies! Wanted to post my latest updates in hope that maybe one of you ladies can relate to me or have expirenced something of this matter as well. 
Okay so let me begin by saying I am 3 weeks & 3 days late! 
I have a 27/28 day cycle. At the most iv been about a day late, my period usually lasts 4 days. In July my period was due to begin July 22nd. We haven't actively been trying in July, well yes we made plenty of love. But i haven't been obsessing with trying to conceive, honestly didn't even think of it. After the 3rd day of my missed period, I decided well I should take a test, although I had no symptoms really I took a test and BFN....no surprise. I decided to wait it out. Well week late, took another test. (Clear blue digital) 5 minutes later, "not pregnant" pops up...honestly no surprise. But what the heck is going on??
Sooo here are my symptoms, if these are even relatated to pregnancy: 
-increase of cm!!! (Like did I just pee myself cm?) loads of it....at one point it was pretty thick but has thinned a lot just large amounts hasn't changed.
-off an on cramps on my left side. Not ovulation cramps or period cramps these are weird there different. They come and go and let maybe 20 seconds like "woah what's going on" to ok "I'm fine" last night they were pretty bad, I had to sleep with heating pad on my side and lower stomach. 
-lost of appetite, not been eating too much, but when hunger kicks in if I don't literally eat something In 2.5 im going to die!! (At least that's what my stomach seems to think) 
-when I smell something on my patient, like poo, bad breath, strong urine (I'm a private caregiver) I could literally throw up its like its burning my nose. Which usually honestly doesn't bother me, I'm use to it. 
-back has been hurting me a lot more then usually
-no sore nippleees, although to me they seem a bit darker. They usually are light brown looking blackish purplish, that's weird isn't it? Lol 
-tired as hell but still for some reason fueled with tremendous energy,!if that makes since? 
-high sex drive 
-I have been frequently urinating, but sometimes I think I have to go & a small drip will come out, which I have been drinking a lot more im SO thirsty. 
-oh also have expirences this a few times! This burning acidy spit up has hit me about two times & iv ever need had that befote( whatever it's from it sucks!!!) 
Anyways that's about all I can think of, if any of you ladies can relate, is it even possible I could still be pregnant just low hormones? I don't know, do you think there could be something wrong, please all comments are welcome 😊 thank you in advance. 
I just started spotting which I find rather odd because I'm not due for period this month until the 25th....Any feedback?
