Hi moms, I recently had a miscarriage March 18. I was three months pregnant..

I recently started trying this month but during my ovulation period it said it was August 8th I still had a line the 9th was super dark and the 10 th a line as well. I notice I spotted after intercourse 3 times one on August 6th and 8th and 10th . Idk if that’s uncalled for I never had that happen. But I’m more confuse because today is Aug 14 I took an ovulation test the line got darker from the other one I took Aug 12 . It look like it was fading My ovulation day past . Why did the line start getting darker again. Thank you for the help.
