What could this be?

April

My period was supposed to arrive on or around July 24th. Yesterday morning while going to the bathroom I noticed some light colored blood when I wiped. I assumed it was my period. So I grabbed a tampon.

Around 1:30 - 2pm I figured I needed to use the bathroom to change my tampon, as it had been a few hours. When I took my tampon out, there was a tiny bit of blood. It wasn’t dark red.

As of today, I haven’t had any type of bleeding to indicate that my period has arrived. Even though I have been experiencing occasional abdominal pain (similar to pains I receive when my period is coming/has came).

My husband has taken two semen analysis tests this year and have came back that he as low sperm. We have been TTC since June of 2018 with no success. I’m NOT getting my hopes up, since we’ve had nothing but negative pregnancy tests this last year.
