scared

I been in labor and delivery for 3 days having contractions and bleeding dark red with mucus and with huge clots size of a plum and they say it's because they checked my cervix but I never had that happened before.... They didn't give me a ultrasound they just put me on the monitor to check contractions and her heart rate.. They keep giving me pills to stop the contractions but it's not working then they say let us know it the contractions get worse and leave put the last time they checked on me was at 11am and it's 2:44 and they just left out just asked was I ok I don't know what to do I'm scared and I feel like something is kinda wrong but they also told me i might be bleeding cause the placenta detached but again no ultrasound just on monitors I'm so depressed and scared have anybody been threw this before? o and they say I'm 26 weeks and 2 days
