I was on the depo shot and after it was time for my next shot i decided to change to another bc but it's been a while since i've had my period and get headaches frequently and im naseaus all the time. I vomit at least once a week. i've had diharrhea for the last 3 or 4 days could i be pregnant?
If there was a lapse in between your shot and getting on the pill, there is always the possibility of pregnancy. Considering the fact that you have missed your period, did you take a pregnancy test? You need to rule that out before anything else.
Secondly, when a women begins a new birth control regime, she may experience several complications with it. Nausea, headaches, diarreaha, sore breasts, mood swings, and lethargy could be a sign that your script is not suitable for you. There are many times that a women may have to go thru 2 or 3 different brands and strengths of pill before she finds the right one that suits her.
I would call my doctor and explain to him/her what is going on. In the meantime, if you think that you may be pregnant, you may want to consider stopping the pill at least until you figure out what's going on. Call your Doctor today and let him know what's going on. I am NOT telling you to stop taking your birth control, i am making a suggestion. Run to your local Walgreens or Walmart and grab a test today, you can put your mind at ease. Then deal with the complications that you describe, which i think are attributed to the new bc script.
