My girl time is predicted on my wedding day

Ugh that's so frustrating. The stress of the wedding might change it again so who knows what will actually happen. I mean you can speak to your doctor and possibly alter it using bc but personally I would just plan to have lots of feminine products, the meds you use, portable heating pads etc. Congrats on the upcoming day! Hopefully it all works out for you

This happens to me sometimes also (a period will be a couple days early or late, or run on a little longer than anticipated). Sometimes my body just resets itself back to my original schedule though; so hopefully that's the case for you! Stress/nerves can affect your schedule also, and I'm sure you've got plenty of that going on with a wedding next month! I don't have any advice on making it come earlier, but there are pills you can take that will stop it from happening until after your wedding! You can get them online from wisp.com. They will just prevent you from having a period until you quit taking them. If you don't have bad periods though, and don't want to take medication to delay it, I would highly highly suggest modibodi underwear to prevent leaks from happening in your wedding dress. They have been life savers for me on multiple occasions!
