Looking for opinions

hey guys! so let me sum it all up. I’m on the pill, sexually active- we don’t use condoms either- but the last month i’ve had trouble remembering to take it at the same time each day ( don’t come for me hahah) but my last period was feb 1, and it was like 3 days- and now it’s feb 22 and the past weeks since i’ve felt how anyone would feel when your period is gonna start, but worse. My breasts are super tender, ive had shortness of breathe, fatigue, my gut gets these weird sensations of pain, and i feel pukey in the morning and at night. Is there a possibility i could’ve gotten pregnant in between or? I’ve done some research but it doesn’t tell me much- Just looking for opinions! thanks ladies
