Hi,
I am so confused. I am currently 13DPO (pretty certain as using OPKs). Since ovulation I’ve been getting on/off cramps. I tested at 10DPO and it was negative. Started spotting yesterday but stopped today so took a test that showed faint line I think (see pic). But now started spotting again and cramping. Cervix v low. Is this likely the start of AF, or is this too late for any implantation bleeding? Thanks!
