My question is, is that Im not saying my tubes are blocked because I hope not but if they were would I still get a positive opk and ovulate
Yes.
Women that have had their tubes tied do still ovulate. The egg just can't get to the uterus.
Why would you think they are blocked? Scar tissue from an infection?
Two months ago I was bleeding for 18 days and i went to the er i was there for 10 hrs they said my sonograms were fine but think i have PID i have never had a std before and i wasnt in pain or anything out of the norm just the bleeding
Did they put you on antibiotics? Have you followed up?
Yup they gave me antibiotics and i did a follow up she said everything looked fine
