I Felt Like I Had Period Cramps And When To

I felt like I had period cramps and when to the bathroom and when I wiped I seen a tad bit of blood noticed that it wasn't my period so I looked at my vagina and notice over the whole of the urethra there was a tiny pink lump covering the hole then I looked it up and it shows that is a caruncle I found out that it was a benign tumor then I looked up more about it and a lot of people said their doctors recommend when it's a small little lump the estrogen cream works was wondering if you know if it works for a caruncle.. I'm 25 years old.. Thanks anything will help right now
