I'm fixing to go crazy!

Im 7 1/2 months ppd. I have a 32 day cycle. I was suppose to get my period on April 20th. (My last period was March 19th) My period for my whole life has never been over a 34 day cycle. Here we are May 1st and no period! I do not take birth control, as I'm not medically allowed because of blood clotting factors. (I had a DVT & PE's with my first baby) My husband and I use the pull out method. It has worked for us for over 5 years. I have never gotten pregnant when we haven't been trying. BUT, this cycle my husband had a week off from work and I think we probably had sex every day. (He still pulled out) (We normally do it about 2-3 times a week) The day after my missed period I took a test, negative. I was feeling like I was about to start.. bloated, moody, diarrhea, headaches... Then Sunday I took another test, SUPER faint line. I then took another test at midnight it was quite as faint but still faint. I've took one almost every day with FMU since then and they are still the same. I'm so moody it's ridiculous, my boobs hurt like I'm still breastfeeding, I have AWFUL headaches, I switch been constipation and diarrhea (which is SUPER WEIRD for me.), I'm so tired throughout the day (but who isn't when you have an almost 3 year old and 7 month old), I'm still bloated, I'm crampy like I'm about to start, I have an increased in cervical mucus (it's like egg whites) and my stomach is so sore when I push in on it. I can't go to the doctor for a blood test til I go home in 8 days, we're currently out of state. Should I contact my doctor? (I'm high risk) Could I be pregnant? Am I just late? I need advice before I lose my mind!!
