Wow, I'm amazed that so many women have this problem. My period has recently (I have an almost 3 yr old) gotten so that I spot brown for 3-4 days before AND after, and then so heavy that I go thru a super tampon AND a super pad in 20 minutes every 20 minutes for 24 hours or so. Yes, be sure you get enough iron. My dr said some women just do this, and the options are surgery or the BC pill if it makes life to unbearable. (I'm so tired of this, can't plan anything, am considering something, although the easy "fix" the BCP, will make my already high bp higher...)
Take care, and a 2nd opinion never hurts. But don't worry too much about it.
Good luck with conceiving!!
