Pregnancy in unknown location ?

I started bleeding at 6 weeks pregnant, lasted a week, I had a transvaginal ultrasound and they said that they couldn’t detect a pregnancy in my uterus other than the fact my endometrial lining looks thick. However she’s said that I have fluid around my right ovary which is where I was getting a lot of my pain during the bleeding .. so she cant say for sure if I’ve miscarried or it’s ectopic. She’s took my blood and will see the difference in levels when she takes them again on Thursday but has anyone had this before ???
