If I get nauseas and headaches on my birth control pills dos that mean I need more or less estrogen?
Difficult pharmacogn. Sometimes the dose-response relationship for hormones is not linear but complex - such as a horseshoe-shape, where side effects are associated with low and high doses, but not optimum doses. So no generalization for you is helpful, unfortunately. Dose titration experi-ments with your doctor's help should be able to clarify this.
Neither. Oral contraceptive tolerance is trial and error. There's no evidence that one combination or dosage causes fewer side-effects then the other. The side-effects you mention are very common but don't typically last more then three months on a new contraceptive.
So I started new birth control pills 2 weeks ago. Are these common side effects? - nausea, body aches, stomach cramps, headaches, ovaries aching, etc
Maybe. It is possible it is from the birth control. The only way to know for sure would be to do 1 of 2 things: continue and see what happens, or stop medicaiton until after period, see what happens, and try restarting. If it happens again then it is the medication. If you get better it wasn't. Use back up protection in meantime. Read more...
