Hi Tinkerbellj - before my VA started I don't think I had ever looked at myself down there , so when I did everything seemed a complete mystery. luckily I had a great Gyno who sat me down ( literally) in front of a mirror and explained all the bits and bobs , I had what I felt was a large lump and it turned out to be my hymen ! So I think since starting HRT a lot of things start to pump up
Maybe that's what has occurred in your case ?
(When my VA first started my doctor thought it might have been a prolapse )
I hope this is of some help
❤️❤️❤️Ss X
