Hey Rachie, i had my period when i had my op done and that was what i was most worried about, in the middle of the night i had to get the nurse to help me to the toilet as i was in lots of pain and was attatched to a drip and had drains in, i use tampons so was able to sort that out but was not able to put another in and the nurse was lovely and got me a pad but i felt so embarressed, in the morning i was taken off my drip and they removed the drains and i was able to go to the toilet unaided which was a relief, as for deoderant i think its just so your totally clean and there is no risk of infection, to be fair i put a little bit of a roll on because i would of hated to be smelly as i had a 2 hour drive to the hospital. good luck xx
