So I had a positive opk at cd14 dtd cd 12, 14, 15 & 17 now on day 19 and has one light spotting which (sorry TMI coming) ... only left a slight mark in underwear

I’m confused... I think this is too early for implantation bleeding, and I did think maybe ovulation but I tested again just to see and it’s negative.

I have a little girl who’s 3 and half, and we had a miscarriage at 10 weeks back in December 2017, and I didn’t have implantation bleeding with either of the pregnancies.

My cycles are regular 29 days, and I’m confused as to what this is, and wondered if anyone had had the same or similar??

Thanks
