dont know what to think

So, we bd 3 times in my fertile window. Iv had one bout of nausea, twinges in my belly low down, my boobs and nipples are not as sore as they usually are by now. I'm not cranky like I normally am, peeong so much. and had pink creamy cm at 10dpo. Thought we finally done it but now I'm 12dpo I can feel a bit of an ache in my uterus like af is about to start. Has anyone felt like af is coming but got a bfp? I'm still 2 days away from af, and it never ever has came early. I feel my ov and it was at my usual time so if af came early it would mean my lp was shorter this month too
