Could I be pregnant?

Je

I had unprotected sex with my husband on August 1st which was the fourth day of my period. According to my apps I shouldn’t be in my fertile window until the next few days.. like ranging from the 7th-15th of this month. I know sperm lives in a female body for up to 5 days so therefore it should’ve all died off yesterday. I’m just freaking out, I think all of it is just paranoia. My family has been asking if I’m pregnant ever since we had unprotected sex. Usually they don’t ever ask. I’m super stressed out. Like I’d be fine with being pregnant but I’ve got mixed emotions on what my family will think if I am expecting. They want me to get out of school which I graduate in December from RN school. Therefore if I am pregnant/do get pregnant this month, I’ll have the baby in May of next year. Ughhh I’m just unsure of what to think.. if I get pregnant I’ll be SOOOOO happy and so will my husband but I’m just scared of what my family will think😭
