Before my son I was blessed with no cramping at all. I never understood why they made so many pain relievers for menstrual cramping... When my period came back, it seems that on day 2 it's the worst, I don't want to move, my cramping is terrible, if I could stay home from work I would, but it seems odd to me to request a day off due to a regular menstrual cycle, so I turn to Motrin to help me thru it. I remember mentioning it to my OB/GYN on my next regular appointment. After my exam the Dr. pronounced me fine. I'm glad you asked this, as it's nice to hear from women with the same issue!
In my case the cramping did start to lessen (I'm trying to figure out when exactly (I'm now 5 mos. preg W/ #2 and my son is ~2 1/2 yrs. old), so I'm guessing around the 2 year mark it finally started to lessen up. I wonder what will happen this next round! ~J.
