Hello, I'm just really worried at the moment and in need of some advice explanation. I had unprotected sex on 25th September and my period was suppose to start on the 9th February but i didn't then the next day I have serve abdominal cramps (like period pain but 10 times worse) I was sweating, feeling sick, light headed and started bleeding this went on for about 40minutes and I didn't think anything of it I genuinely just thought it was that time of the month where I started my period but I only bled for 4 hours and then it stopped. Then the next day I started to have a normal period. Been speaking to a friend and she may think I may have had a miscarriage? But i possibly couldn't have had one, 2 week after having sex, right? Anyone else been in a similar situation or know why that had happened??
