I've had 3 miscarriages in less than 2 years so needless to say when I took a HPT on the 19th (this month) I was shocked but still scared. I found out with the last miscarriage that I have low progesterone. I miscarried around 5-6 weeks each time. My doctor told me that my progesterone level should be around 20 by about 5-6 weeks and mine was 8.5. So when I got this BFP and I mean positive..every single test I've taken since then the line is just as dark! I went to my doctor last Monday, Wednesday, and Friday. My levels consecutively went from 285 to 612 to 1538. My progesterone is at 70, which is great. I've been feeling a little nauseous, and my boobs have been sore, also it's felt like there's a small rock sitting in the bottom of my uterus. What's worrying me is that yesterday, I just didn't feel pregnant. I'm not sure if it's because it's still early..and I know every pregnancy is different. I was around 7-8 weeks pregnant with my daughter before I found out and it was like as soon as I saw the test, the next morning I was sick throwing up. I noticed if I just sit still, I can feel a little pain in my boobs but they definitely aren't as sore as they were a few days ago. My nipples still hurt a little..and it just seemed like there wasn't anything "there". Am I over reacting? Can symptoms come and go like this, this early? I also use the Ava bracelet and normally in pregnancy your breathing rate, pulse, and temp go up..and mine has been going down. I haven't had any cramping. The first sign for me each time, was brown spotting and it would literally happen within a week of finding out I was pregnant. My levels were NEVER this high the last 3 times, HCG or progesterone. They told me last Friday that my levels were rising great and I have my ultrasound next Tuesday, February 5th. Am I crazy to still be taking those cheap dollar tests every morning, just to see if the lines are staying dark? I know we can't post pics of tests, but every single one I've taken since the 19th (including this morning), the lines are just as dark.
