I had unprotected sex with my male friend (I"m female) 7weeks ago now. I had a rapid test done today and it was negative. The guy at the clinic said that he has never seen one come back different at the 3 month mark then what it was at 6weeks. I also seen my gyn today who said that I'm probably okay. I will go and retest at the 3month mark but what is your opinion on this?

I can't answer your question but I would like to know - because you have done exactly the same as me.
I am going for an 11 week test next week after a neg 6 week duo test.
I wasn't even going to bother to bother but I started getting pins and needles and pain under my arms at 9 weeks so I am as scared again now as I was at the 6 week test.
Absolutely terrified is actually nearer the mark.
