Last period was on November 24th and it was normal. Didn't get one in December but Then, in January I had a light flow for a day. Just enough to use a panty liner. Next day got a little heavy but only enough to fill a panty liner. Third day, I was spotting dark brown with yellowish CM. Lasted two days then it stopped. That was the last time I had any kind of flow coming out. It's now February 13th and I still haven't received AF. I took many hpts and they all came back negative. I'm just curious as to how long it takes for a positive hpt can show. I am TTC with my boyfriend. I have normal periods so I'm wondering why I'm not having them. Am I pregnant and the hpt isn't showing me? I just want answers.
