Is it okay for me to start my birth control?

Hi,
Welcome to ehealthforum,
If you have been sexually active after your last normal periods, do not start with the birth control pills as you will not be sure if the amenorrhea is due to pregnancy or any other problem. Consider revisiting your doctor/gynecologist for a blood HCG test to confirm/rule out pregnancy accurately. If pregnancy gets ruled out, your doctor/gynecologist might want to induce your periods (by giving specific hormonal pills). Once you have our periods you can start with taking the birth control pills as instructed. Be regular with taking the pills at scheduled time daily. Use back-up protection if having intercourse during first few weeks of starting with birth control as most hormonal birth control methods start giving you effective protection after about 3-4 weeks of regular use.
Take care.
