I have been on various birth control pills off and on for the past year and a half. Two weeks ago I went off of the pill altogether (on 10/23). One week later, I had unprotected sex with my boyfriend: once on 10/29, twice on 10/30, and twice on 10/31. On 11/2 I started feeling short of breath and overly tired. Since then I have gone to bed at around 6:30 and slept for 12 hours every night, but I still feel exhausted. I also have been very hungry and thirsty all the time, extremely nauseous, and sometimes dizzy when I haven't eaten in a few hours. I've also noticed that I've had a lot of gas, heartburn, and while sometimes I have diarrhea, others I find myself straining. In addition, I have bloating, severe headaches, pain in my lower back and abdomen, frequent urination, an increased amount of vaginal discharge (with no itching or burning), and I have been very moody. Many of these symptoms seem like PMS but are very uncharacteristic for me. While on the pill, my period came every two weeks and my next expected period was two days ago (11/4)...I have yet to start. I don't know if coming off the pill has had an effect on this or if I might be pregnant. Please help!
