Hoping someone else has had this problem.....I'm WORRIED...

I have been with my fiance 7 years but have never had sex (I'm 26...). We have tried a few times but never been able to 'get it in' for want of a better term! Decided we would wait and it would happen as and when.....

Since then I have started to experience pain off and on when inserting tampons which is becoming a more regular thing....

Then I recently had an ultra-sound as my doctor thought other symptoms I had (excess facial hair unfortunately) my indicate PCOS. Whilst I was there the nurse asked if she could do an internal scan which I did not object to - I wasn't particularly worried........she tried very gently for nearly 10 mins to get the camera in far enough to be able to get any info and it was SO painful I had to ask her to stop even though she hardly got it in there....I even bled afterwards and felt tender and uncomfortable....

I'm REALLY worried that something is really wrong with me....

Any advice????
