Signs of an ectopic pregnancy?

This is my 3rd pregnancy and I’ve never been thru this with the other 2. I had to go to the hospital today and they did an ultrasound but i’m only 5 weeks pregnant so of course nothing but the sac and gestational age showed up, the Dr said I have a cyst on my ovary and I could be on my way to an ectopic pregnancy… has anyone else been through this and everything has been just fine? TIA
