Kind of Embarrassing Question..

daw_etc

Hi, I'm not sure if this is the right place to ask this question...I was hoping someone had this same issue or had some insight; I can't find answers anywhere else so here goes..I am 24 years old..
When I was in high school (and even after) I had fairly small breasts. Proabably starting about two years ago, they grew suddenly to still not very large but larger than they were. I got stretch marks from them and all that (not really bad but they're there). Anyway..I did gain *some* weight around that time so if could be some fat, but I really didn't gain much more than I'd already had. My point is this: Now in the last few months I have noticed that one breast is very obviously larger than the other. This is not just me being critical; it is probably a bra cup size larger (or is the other one smaller????). I was wondering if anyone had any problem like this that was fixed by losing weight?
Another point is that I had been taking hormonal birth control pills for 8-9 years (with one break of maybe a year in there somewhere) and a few months ago I quit taking them..which would seem to coincide with me noticing the breast size difference but I couldn't find anything online about this...only about them shrinking after stopping pills. I don't have a doctor I can ask. Has anyone had an issue like this? Will they go back to normal? Will weight loss make them even?
Thanks for any answers!
