Help please

Samantha
OK so af was suppose to show her face two days ago and nothing...... I took a test and it was negative but I didn't use fmu... Now I have a sharp pain in my vagina... Well that's what it feels like... I don't know what it could be I have never had this happen before af EVER.... Has any body had this problem??? Any advise will help but please no negative comments I'm trying to keep positive.. I have been reading that it could happen in the early weeks and late weeks in pregnancy.,..
