HELP, please, implantation? Spotting? STI?

Cynthia • 💋Cyn

So, I’m unsure… I am CD 22, miscarried middle of July! Had irregular periods until last month (first normal cycle since miscarriage). Today I wiped and saw this:

I have had implantation bleeding similar to this with all 3 of my pregnancies (all ended in miscarriages). Help with your experiences and opinions please!!!!

TWIST: my husband had been having an affair for a while, so we divorced in August (2 weeks after my third miscarriage) I tested and was clean.

But I’ve recently been seeing someone, we said we were exclusive, hence the STI question. We haven’t been using protection because (Exclusive) and he had a vasectomy with his ex wife after they had their girls (I didn’t ask the timeline). So I am worried of an STI, I have never had one before! But I am also unsure of possible implantation bleeding, we have sex regularly. I am pretty sure I ovulated a week ago and we did have sex.

Any opinions and advice would help, my period is not due for another 7-10 days.
