January 10, 2018 I had protected sex with my boyfriend with the use of condom. He came inside of me lil by lil. I mean insert it for 5 seconds, then release then insert it for 5 seconds. That’s the flow. It lasted for like 5 mins. ( this is my second time to have sex in my entire life) I had my period January 17, 2018 it lasted for 5days and it was really heavy. Now this app says i’m 8 days late. (Maybe Due to stress I dunno of worrying that I might be pregnant) I’m feeling all the symptoms of having a period like one week pelvic pain, backache, and cramps , sore breasts, and bloating. . Should I worry? Your response is much appreciated.

Btw, I’m regular with it comes to my period.
