So I have been on the pill for 11 years nows. I last had my monthly period on September 1 and started my pill on September 5. My boyfriend and I had unsafe sex on September 11 in which he ejaculated in me twice. I missed my pill on September 11 and 12. I took 2 pills on September 13. I continued with my pill as normal until September 17. I missed 4 pills after that and got an early period. I decided to stop the pill so that my period could flow. I had a light watery red period for 3 days. I haven't taken the pill from since then. Now am feeling nauseous and I am having headaches everyday. I don't think am pregnant because I had a period. Can it be the affects of stopping the pill? Please help.
