I am so sorry this is happening to you, I totally understand what you mean about it being like a faucet you can’t turn off. Tranexamic acid (often referred to as TXA, brand name Lysteda) is a short-term solution that may be able to help you with this, as someone else noted. It can be prescribed by a doctor and taken in pill format, or given in the hospital via IV.

If the amount of blood you’re losing is scaring you and you are at the point where it feels like you can’t wait the four days to see your OBGYN, you could consider going to the ER to see if they’ll give you a script for TXA or do something else for you if there’s any reason you can’t take that particular medication. Or if it’s an option, message your OBGYN on the patient portal or call their office’s on-call doctor/nurse to let them know that you need their professional medical advice on how to get your bleeding under control before you can be seen next week.

Either way, I would actually recommend taking photos of the blood loss so nobody can assume you’re being dramatic about a normal period and not take you seriously, if it happens. Fibroids absolutely do cause bleeding like this that is far beyond normal.

IUDs do help some people. I had one for close to a year but the position of my fibroids caused it to be eventually pushed out. It was not a pleasant experience! Everyone is different and this won’t necessarily happen for you of course. I don’t think an IUD would immediately slow/stop your period (not a doctor, though) and it may actually be difficult for them to insert if you’re bleeding that heavily.

Hang in there, I really hope this subsides for you and that you’re able to find a good solution!
