I thin your vaginal walls could be a bit dry from lack of hormones, very common, try ky jel , and look into bio-identical hrt, I know many women wish to avoic hrt its a very personal decision, bios helped me tremendously. A good source of info is to go to Mary53 and read her
journal on bios. its really informative, and btw,,a bit of pink bllods not too bad if it continues to concern you, please do call your dr for an appointment especially if you have any pain too.
