Hi ! So I’m ttc cycle #2 and i used opks to track ovulation and had sex those day and I’m now either 8/9 dpo and my period isn’t due till 5 more days , I have regular periods but it’s never early and wiped right now and saw this it’s kind of pinkish , can someone please tell me what this might be ? Also had sex like an hour ago idk if this helps too.
