My husband came inside me a week before my period i still got my period but it was 3 days late can i have a chance of been pregnant?

Unlikely, but...: There is always a chance, especially with unprotected sex. It's unlikely, if you got your period, but a quick way to make sure is to take a home pregnancy test. Providers always check for preg before xrays, surgery, starting certain new meds, regardless of when a woman reports her period, because it's always possible. Please use protection and speak w/ your doc about contraception. Take care.

Maybe: Stranger things have happened. Was it a normal period? Vaginal bleeding is not always a period. Sometimes you can get implantation bleeding with pregnancy. Check a pregnancy test. If negative check again in 2 weeks. You can also see dr for evaluation.
