I went for a doctors appointment and was prescribed this. Mainly because I’m throw up each time I’m on my period and it’s irregular. I also am sexually active. I have read the pamphlet and I’m a little confused as the doctor didn’t explain, just told them I am sexually active and throw up on my period, so they just prescribed me this and that was it. No explanation. After I read the pamphlet It said to take another like a placebo or after 4 weeks. I’m not sure as where I get that pill. Like do I go back to the pharmacy for it? Do I call the doctor to send the prescription to the pharmacy so I can get it? And then do I take birth control the same day as that placebo? I’m so confused! Still new to this and nobody taught me anything about it.
