I have a 3 month old little boy and my periods had been regular since having him. I had sex a week ago and was due on my period about 4 days ago. We used a condom but it fell off without us realising, he didn’t finish but I looked it up and it says there is still a slim chance I could be pregnant due to pre-ejaculation.

My period still hasn’t come on, anyone think that I could be pregnant? Any suggestions x
