The best thing (& cheapest)is for your husband to have a vasectomy. This is the ONLY thing that is complete safe for YOU and it can easily be reversed when you are ready for children.
Or, of course, there are the old fashioned methods:
condoms (most men won't wear them), rythym, diaphram,
O-ring, abstinence during 'fertile' days (they have
this down to a science - it's not that hard), etc.
N., I would stay away from ANYTHING & EVERYTHING that alters or interferes with your normal monthly period. Our bodies are made to function that way. I would be afraid to take anything that stopped your period. Where is all that blood supposed to go? The pill doesn't actually stop your periods, it simply regulates them. Yes, you have side effects, but women can experience a multitude of things during her cycle: mood swings, cramps, nausea, headaches, irritability, depression, weight gain, etc. But her body is functioning normally - I wouldn't do anything to stop that.....you don't know if it would lead to blood clots, aneurysm, brain bleed......of course they're going to list the side effects (from the trials). Keep in mind that in a study of 10,000, if only ONE person has a symptom, they must, by law, list that as a possible side effect.
I think there is also something the doctor can inject in the leg under the skin that makes you infertile (or the male temporarily sterile), but I don't remember what it's called or if it for men or women.
It's a hard decision. I guess I'm from the old school ... don't mess with 'mother nature' or God, or whatever you want to call it. I think it's dangerous.
I heard that they can reverse tubal ligations now - I don't know if it's true or not. That doesn't stop anything except the fertility....you still have the period. But, when your husband could do a simple 30-minute reversible procedure and it would save you so much physically and emotionally, my vote goes for that.
Of course, some men are very touchy about things like that. Some men won't even have their male dogs/cats neutered ... .... go figure!
Good luck.
Oh, if you keep hurting - if this is not normal for you each month, please check with your OBGYN - I did that once - for about 11 days .... turned out I had an ectopic (sp?) pregnancy/miscarriage....
