I'm scared

I'm 14 weeks pregnant, had my scan last week and everything was ok! I finally thought I was over the danger stage! Only thing was I have a cyst on my ovary! 
​Yesterday after I had intercourse with my husband I wiped and there was blood, no pain or cramps. I have been spotting on and off since then! I am so scared I went to hospital and they just told me to go home and rest I didn't get a scan or anything. I don't want to loose the baby
