27, 2 periods a month with severe cramping, loss of labido...ablation or hysterectomy? possible TMI?

Ok, I have 2 appts. with two gynos next week but thought I would see if anyone had first hand experience. I have always had short cycles (about 21-26 days) with heavy bleeding and SEVERE cramps. I gave birth to my 3rd and last baby 6 months ago and since my periods restarted (about 8 weeks after he was born) my periods have been coming every 16-18 days apart. My periods last between 5-8 days, so you can imagine how frustrating it is to feel I am on a never ending period! :( Before my so,n I ALWAYS knew when my period was coming because I would cramp so bad days before. NOW, I don't get cramps until about the last day or so and it is SOOOOO bad I can barely go to the bathroom without wanting to pass out..(sorry TMI) I know I am done having children but because you still get your period with a tubal, that is not an option for me. I will be talking to the dr.s about an endometrial ablation or a partial hysterectomy. Have any of you had these procedures, and have you had them this young? What are your thoughts on the subject?
