Hi, I had unprotected sex with my boyfriend and he came inside me and 3 days later I came on my period because I was due on but it isn't regular to what it normally is, it is normally heavy! But its really light + I spotted a line of brown? Does this mean I could be pregnant, its to early to test please help?

It is a possibility but there is no way to tell for sure for a week or so until you can take a test.

It is too early to tell, in a couple weeks, you may go to the doctor. Since it is so early, you may even have to wait a few more weeks for a accurate test.

But yes this is a sign of pregnancy

Thanks for your advice, il go and see the doctor in a few weeks, :)
