heeey 🙂 no it doesn’t at all, i was on my period during my op (just what i wanted, nott) and they just give you a sanitry towel to wear, which is horrible in the hospital pants! but still can have your op done, just let them know 🙂
I was on my period when I had my BA and I just had to wear a sanitary towel as I wasnt allowed to use a tampon due to the increased risk of toxic shock syndrome.
