Help!!!

So I’m on cycle day 35 and usually my cycle is around 30-32 days. Last month my period came on cycle day 34. My period has not come yet. I had sex maybe 3 or 4 times within the past month. I’m not on any form of birth control but he does wear a condom and pulls out (Not just one or the other- BOTH, every time.) I know there’s always a chance with having sex, but do you think there is a high possibility that I could be pregnant? I’ve been having very common PMS symptoms such as sore nipples, mood swings, and gassiness. Am I stressing out too much?
