Tilted Uterus?

I got told by anurse practitioner that i had a titled utuerus and thats why i couldnt see my baby when i was 6 weeks. Well ever since about 5weeks of pregnancy ive had pelvic pain. When i sit or lay down or get up sometimes when i cough and im currently 15wks and over the time it seems to have progressed. Anybody else have this issue? My doctor told me i was pregnant its normal to have pelvic pain.
