Hey all! 10 weeks ago, I had unprotected anal sex with a guy. I have irregular periods so I regularly use Primlout Nor to get them and I usually get heavy ones. Last month however, it was so so light as if it’s just spotting and this month I didn’t get it at all though I took Primlout Nor for 5 days . I tested for HCG after around 26 days of the intercourse and after 9 weeks and it all came back as negative. Might it be a false negative ?
