I had sex with my boyfriend almost 3 months before it was protected as well just once at night he used condom he said bt as I was drunk I'm not too sure.I got periods for 2 months this is th 3rd month almost 35 days got over I'm not getting periods yet.Is there any chance of getting pregnant while having sex 3 months before.

My periods are always irregular it use to delay by a week or early also it happens.Doctors hd avised me earlier nt to gain weight as my hormone levels were abnormal.So I will have irregular periods if I gain weight.But nw I'm getting scared am I pregnant by any chance as I know that I hd sex.If anyone can answer my query I will be very grateful as right nw I don't have any source of help as my boyfriend has dumped me and married another girl and I can't inform my family.Please do help me by answering my query.
