I need opinions

The hearts are when me and my bf has had sex

On the 14th we had sex as u can see 5 days later lol and we had unprotected sex which that’s not unusual we’ve had unprotected sex since we been together and I’ve been off of my bc for over a year now but on the 14th he came in me and I had this light pink discharge come out

Idk if it was my cervix irritated even tho he wasn’t deep in me or implantation bleeding I’m currently 3 days late today my boobs are really heavy and swollen I’m always tired and I’ve been craving salads and pickles . Very emotional and I keep having to change my panties bc my panties keep getting wet and I’m not peeing on myself lol any opinions
