Pregnancy Info HOME

I've kept track of my BBT for 2 years. On my current cycle I had erratic wake up times & several missed temps. I decided I didn't have the info for an accurate chart. I quit taking temps & figured I'd start again with my next cycle. So I have no idea when I ovulated. Over the past 2 years my average cycle was 30 days. I had one 44 day cycle. Due to work schedules my husband & I didn't have sex for days 7-27. So when day 30 came & went with no period I figured there was no way I could be pregnant & this cycle was just going to be a little longer than usual. When day 44 came & went with no period I began to wonder if the sex on day 28 could have been the right time for us & I actually got pregnant. I took a test today (day 46). The control & negative lines were light but definitely really there (3 or 4 on a scale of 1-10). The positive line was a 10. Any positive line is supposed to mean pregnant. But if the test was valid why are the control & negative lines much lighter? Am I pregnant?
