Ovarian cyst

Patricia • 28 years old and have two girls ages 7 and 9. Just had my first miscarriage (7 weeks) rip little bean
Ok so I found out I was pregnant last week. My last AF was jan 31 so would put me at 4 weeks and a few days. Today I noticed a bulge on the right side near ovaries that was throbbing went to er they didn't see sac but my blood work confirmed pregnancy 1-3 weeks and so did ultra sound an they found a few cysts. Since than the pain has gotton worse. I'm scared its eptopic even though the doc said its not. Help!!! Anyone else have this happen
