My name is Lina and I just switch to a different type of birth control almost a month ago. I was originally on the implant for a little over a year and I switched to the pill. I haven't been feeling very well. Everything I eat makes me feel like I'm going to be sick. I have cramps on and off throughout the day. Smells bother me and I'm more moody and want to cry over a lot of things. Should I be worried about being pregnant? I've had unprotected sex multiple times since I switched. I read I should have started the pill 7 days before implant was removed but I started it literally the day after it was removed. Any advice?
