Hey I'm at my wits end, I'm on my period and I've been using tampons-daytime pads-night since last night I've been experiencing EXCRUCIATING pain when peeing quite like cystitis and when it occurs o cannot leave the toilet. I don't go to the toilet when my tampons in to avoid cystitis as I used to get it fortnightly but I really need help its 03:36 AM and I've been stuck on the toilet for two hours, I cannot move as the pain is so bad and stings and itches any advice please help. I'm 15 by the way
