So, two weeks ago, on Thursday January 29th to be exact, I took an ovulation test, it came back positive so my boyfriend and I had intercourse Wednesday, Friday, Saturday, and Sunday. Then, exactly a week later, on Thursday February 5th I took a HPT and it was a faint positive. So, I decided to wait a few days to make sure they would get darker. Then on Sunday night and Monday morning, I took a clearblue digital test, and they both said pregnant. Then, Wednesday night, I took another one that came back very dark, and one this morning morning. My period is expected tomorrow, and according to Glow <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a>, I'm 3 weeks and 6 days pregnant. So, when I took that test that came back positive last Thursday, I was exactly 3 weeks. Do you think I have a high level of hormones? Just curious, because I had a miscarriage at 4 weeks back in December because my hormones weren't rising accurately and doctors aren't seeing me now until I get my insurance switched over so I'm in a bit of a predictament right now and trying to test everyday to every few days just to be safe until I can get into see a doctor in 2 weeks.

These were taken at exactly 3 weeks pregnant. (The 3 purple tests) clearblue taken Sunday night and Monday morning. The 2 thin strips were taken Wednesday night and this morning.
