Had period 1 1/2 days...

So I had my period for a day h a half... NOT NORMAL for me.. my child is 11. So it has been forever since pregnancy has been my thing. Yes, I am trying to get pregnant, but this threw me off. Been holding off on a pregnancy test because I took 2 in June only for them to be negative after being sure that I had to be pregnant. My partner & I literally have sex at LEAST once or twice a day, sometimes 3. In the last 3 months we have maybe skipped 4 days total. I am 28 & I am afraid my ovaries are giving up on me after 11 1/2 years of not trying to conceive at all. What does everyone think of the short lived period?
