Hi E.,
I'm sorry you're going through that...it's a total pain in the neck! I had my first 3 1/2 years ago and prior to him I was very regular (could set my watch by it), had 4 to 5 day cycles, and no cramping (or minimal for about an hour the first day if any that cycle). In college I had one time of an irregular period where I had my period for 14 days and it was heavy...I was totally anemic (so if you're heavy, make sure to keep your iron levels up) and had to change myself so often I was sore! Okay, so fast forward to these past 2 1/2 years (i nursed Robbie for a year and never had a period). I was having terrible pains, even while I nursed. Once I stopped nursing I got my period, it was irregular (from 2 weeks between to 6 weeks between mostly heavy and the cramps would send me to bed all day for at least 2 days) Turns out I had endometriosis and was annovulatory part of the time. We just adopted our 2nd child after trying IUIs and IVFs since we couldn't conceive, and my cycle is just now getting back to normal (could be the hormones managed to push me back to the 4 week cycles with 2 days spotting (never had that before and it's a pain, but a panty liner works okay), 2-4 days bleeding. I would say get checked out, I know I put it off for months and while I doubt I made it worse, it was good to find out what in the world was going on. Good luck and take care of yourself.
M.
