Re: Severely constipated during first day of period
I don't know much about Maca root (sounds like something I should look into!), but what you're going through sounds completely normal. Your periods/symptoms are going to change over time, so you're probably not going to have such sever discomfort forever.
For now, if you're not going to go on the pill, which will regulate your hormones and make the cramps & pms less severe, I would suggest taking Alleve at the very first sign your period may be coming. Taking it before the cramps hit really helps. You can get prescription strength too if you need it. And of course drink lots and lots of water. Try working more fiber into your system slowly. Yeah, laxatives are not a good choice.
My symptoms were kind of reverse with diarrhea just before/first day, then constipation. When I was your age I didn't have any PMS, just the cramps. Now at 36 there are no cramps, but I have PMS before.
If you're cycle length remains fairly regular, there's probably no need to see the Dr, except for your yearly pap smear check ups.
