Positive OPK 12DPO

Ronnie • Nurse Mom to a little boy Baby #2 on the way

On the 10th I had a positive digital OPK (peak) which would be cd15. The day before was negative. Well 2 days after that positive OPK I had some bleeding I thought was my period. It only lasted for about 3 hours. Well approximately 6dpo I had some spotting. Nothing that even lasted long only when I wiped like 2 times I went to the bathroom. I’m 12DPO and got a bfn. I read somewhere that it would take 7-12 days after implantation to have a positive test but I’m just curious if anyone has had this happened and ended up getting a bfp. I read that could have been an ovulation bleed but I find it weird that I actually got a positive digital and then that happened. Ugh. TTC can be so hard.
