So I have suffered 2 misscarriages in the past 2 years.

My period started on 28th July and finished around 1st August. I had unprotected sex on 8th August and he came in me, I then had unprotected sex on 12th August, and again on 15th August, although the last two times he didn’t cum instead me.(Even though precum is still a possibility) I would be ovulating around this time I guess, today being my last day of ovulation according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>, however just now when i went to the toilet I noticed some pinky/brown discharge in my pants, so i wiped and had a little more, I then wiped again around 2 hours later and there was a little more. Could this be ovulation bleeding? Although I’ve never ever had that before, or could this be Implantation bleeding as the timing would make some sense but i dont know.. i just don’t want to get my hopes up but need some advice... my best friend has just found out she is pregnant with her second baby and so I’m praying that I am too...
