Condoms and pregnant

Shaye

So I had sex a few times after ovulation and we used a condom and pull out. But now I’m a day late. Can it be from stress and paranoia?? I don’t want to be pregnant helppppp(note: I had my period symptoms (sore breasts and acne) like a week ago) I was also extremely sick for 19 days in a row a week ago…can that effect my period?
