I had unprotected sex a week and 3 days ago. He didn’t cum nor am I on birth control. My period is a bit irregular and I usually get it around the end/beginning of the month. Last I got it was February 1st. My boobs are a bit sore and I feel really bloated. I’m also prone to back pain so I don’t know if that has anything to do with it. I haven’t taken a pregnancy test and according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>, I am 1 day late. Should I worry ?
