Were you able to get to the doctor and start the pill to postpone your bleeding for after the wedding and honeymoon?? Let me know!
Ugh, I don't think the Primolut-N would do anything to help you at this point. It actually has abnormal bleeding as a side effect (spotting). So, I think you are stuck. The time to postpone a period is before it actually happens but once it is going, it's hard to get it to stop. Can you give your doctor a quick call to see if they have any suggestions? I've read some home remedies such as taking ibuprofen (normal dose). Not sure HOW that works but it's on the list of ideas. vitamin C and iron rich food promote clotting. So, that's supposed to help. And drinking a lot of water helps flush the system a bit faster.
Sorry, that's about the best I've got. Hopefully your period is like mine and it is more light the last two days. Good luck at your work function. Let us know how it goes.
