Hi - I'm 29 and over the past month, I put on a few lbs and have been cutting back to lose them; right now I weigh about 133lbs, but I was up to 139lbs. It's been a lot easier to put on weight since I've been on birth control (I weighed 110lbs before I started taking it - I do account for about 10-15lbs of that in breast/hip/butt growth, so I'm not going crazy with weight loss).
I've been on loestrin for 2 years now, and I haven't had a regular period since I've been on the pill until recently. Before I went on birth control I'd have debilitating cramps on the first day, a really heavy flow until the third day, and it would last exactly 7 days. I'm still on a period that started July 28th, so almost 2 weeks now. It's dark colored, a lighter flow, but still enough that I need a panty liner, and I have clotting.
I also have occasional menstrual migraines. This time around, I had a very nasty one: I had an aura and was unable to see out of my left eye prior to the headache. I took advil, drank hot tea, and slept it off.
I did not take any medication other than birth control and what I took for the migraine. I don't have any cramping or discomfort. I was moody the week before.
