I'm 17, and my cycle usually isn't normal. The mast two months they have been. (July & August) I start on the 19 and end 5-7 days later. I haven't gotten it this month and I think I might be pregnant. My S/O is Active Duty Infantry and is currently deployed. We've been trying for some time, stoped due to the deployment. I use FertiliTea for two days (four days before he came home) I was also told I have Hypothyroidisum but my levels were fine (PCOS three years ago, but had 1 cyst in January) I've taken a few hCG home test (strip kind) and they are all neg. Is this normal?
