Am I pregnant ???

Ok so the last time I had sex I was on birth control. But, then there was this whole thing w/ me switching doctors, so they stopped sending them to the pharmacy near my school. After that I bleed lightly only for like 4-5 days & my normal period is heavy ! After that I thought everything was normal .... then I started having symptoms. I ignored those and thought well maybe it’s just pms. However, my mom questioned me and asked if I was pregnant ( Mother’s intuition ), my best friend commented on how huge my boobs were and even my stomach ... then my “period” was a little late. I took multiple Urine test & they all came back basically negative .... yet I still had no period. I went to a clinic and everything. While all of this was happening I developed these really intense cramps mostly directed to my right lower abdominal area. I ignored it for weeks. Then one day I just started spotting, it was really light pink and well I was told it was normal for early pregnancy ( the clinic assumed I was 4 weeks which was why I was getting negative results because it was too early ). As the day went on maybe around 6 p.m. the cramping on my side became so bad like It literally hurt to walk. When I got home I was bleeding like I never bleed before. It was thick w/ clots and a weird mucus like texture. Soon after that it was just clots. With my period yeah I have small clots and heavy bleeding but this was like a big a** clot followed by smaller ones for the rest of the night. I couldn’t sleep and I was in so much pain so I went to the ER. They took blood gave me a regular ultrasound and a transvaginal ultrasound. The hospital I went to was really bad and didn’t ask me if I had questions or really tell me any of my results. They only thing they could say was aside from a ruptured cyst I had there was also a sort of mass there ( like a sac ) .... soon after that I started to bleed again very lightly though. Anyways Since they were so horrible I scheduled a obgyn appointment for my thanksgiving break. They were equally as horrible as the hospital ... they gave me a urine test when I specifically said that doesn’t work for me. My initial hcg level was low but again there were some complications. I’m just really confused because a woman knows her body better then anyone else and whether I lost that child or not there are changes that I can’t control w my body and it’s scaring me. My boobs are huge, I’m always  nauseous, I literally don’t have an  appetite and when I do I want to throw it back up, my stomach has grown slightly and is kind of firm but not too firm at the bottom. If I am pregnant this will be week 7... because of my worries I was told that I should wait till week 8 or 9 and get another beta hcg test. Could it be possible that the antibiotics I had to take are effecting the results or could it be that my body literally wants no one to know but me ??? I need some serious advice. ( btw my honey pot went through some bag things throughout this .... some bacteria and some other infection which is why I mentioned the antibiotics ) oh and I gained a few lbs
