Thoughts anyone?

Ok I have two kids already so I feel I should have more instinct here but I think I’m crazy. My husband and I did it two days before I ovulated and he didn’t pull out quite quick enough. So stupid I don’t know what we were thinking 🤦🏼‍♀️ anyway we didn’t do it again but I’m now 11 DPO and have taken like 5 tests both pink dye and digital (all first response) and they were all negative. My period is due in 3 days but I just don’t feel right. My stomach feels like there’s an air bubble in it when I suck in, Ive been having head aches, super cramps and diarrhea (sorry tmi 😳!) but I don’t usually get PMS type symptoms until the day of or after my period starts. I just don’t usually get these symptoms before hand. Am I crazy? I wouldn’t think all these teas would be negative three days before my period if I was really pregnant. Thoughts anyone? I’m going crazy!
