It certainly would not hurt to call your doctors office and talk to his nurse, but I will tell you mine did not improve after childbirth. I developed PMS and sometimes cramped horribly. It progressively got worse as I aged with extremely heavy periods, and around age 40 I finally got a hysterectomy. That cured it.
I am not suggesting this for you! I assume you are younger and its not that bad, but I do think some GLA (a supplement that balances hormones) would be worth a try. I did not know about it back then, but now I am a Shaklee Distributor and so i take Shaklee. I trust it. If you know a Shaklee Distributor you might try it and see if it at least helps some. Again..... it certainly would not hurt to talk to your doctor. I don't think there is anything seriously wrong, but she may have some advice that would help.
Good Luck!
