I am worried my birth control is becoming less effective?

I have be on the pill for a little over 5 years very soon. In the last few months I hold noticed my spell has become much heavier and I hold had pretty unpromising cramps. I am worried that my birth control is becoming less important. I also know that they say the pill is best for women averaging 140 lbs. and I weigh more than that.Just wondering if anyone have any suggestions or input. Thanks!

What's the best way to shave down nearby?

Keep in mind that nearby are dozens of kinds of birth control pills. If one stops working at controlling your period (which happens to profoundly of people), you talk to your doctor roughly switching to a different pill. If you're on a low-dose pill, that could be part of the problem. High dosage pills control period better and prevent pregnancy slightly better, but you do experience more side effects with them. But, markedly talk to your doctor. It's totally mundane to have your body chemistry renovate over the course of five years, and there's a BCP out within that will suit it better than the one you're using now.
