please help 😭

Okay guys. I'm terrified! I haven't had a period since October 30th. It lasted until November between the first and second. It was unusually light. And about a week early. After that, I had to come off my birth control due to pharmacy issues. I told my boyfriend and 3 days later (November 5th) he came in me. Since then, I'm constantly constipated. I have pms like cramping. Lots and lots of discharge. And lately, my boobs are SO sore. Not just my nipples, all my boob! I've gained a pound or two as well and I'm very moody. People all around me tell me I'm pregnant from my symptoms, but I don't know. I took a test about a week and half ago and it said negative. But my friends mom said that some women can't get positives and have to take a blood test. (I did take that test at night.) what do you guys think? Sorry it's so long...
