OP YADNBU. You have my utmost sympathy. I also have insomniac teenagers.
I have just got back from holiday where our bedroom was at the opposite side of the very large apartment. I had plans.
I was taking Cerelle, started flooding at the airport. Dealt with flooding and carried on. On holiday it continued, one morning after waking up in a murder scene I stopped taking the pill that was causing the flooding.
Big mistake. Huge. For the next few days I was going through super plus tampons in less than 30 minutes. On one memorable occasion, I changed it, left the loos, felt the gush of doom and had to change it again. 4 minutes. Thank you Kennedy Space Centre for your free tampons and maxi pads or I couldn't have lasted the day.
Check your bathroom cupboards, medicine cabinets, purse, handbag etc. I thought I had some Norethisterone in my purse but the pack was empty.
I know some people happily have sex on their period but a) DH won't go near me and b) clots the size of your fist aren't very arousing.
I hope you can sort something.
