It will be alright, trust me. I had my surgery on 12/02/17, got my period in the morning so I took with me my overnight always pads which I feel comfortable in. I was so nervous and irritated that this had happened on surgery date. As I whispered these facts to the nurse as I was getting ready (taking clothes off to put hospital stuff), she handed over hospital panties and gave me a big weird pad, then said: it’s fine, this happens all the time, it’s usual and there is nothing to be ashamed off... I was so happy and relieved to have special panties and not worry about being fully out while on my period. To make things better, I asked if I could change to my own pads and they were like sure!! I was relieved! The pads from the hospital were not comfortable at all. I was so happy! Just take a few things with you and you will be fine: baby wipes and your own pads (in case you get your period too). You will be fine. Good luck!
