Ok so Sep 25 I had unprotected sex with my bf i took plan b the morning after. Again at the beginning of oct (unprotected) but again took plan b the morning after. I got my period or what I thought was my period oct 9 on time. it seemed pretty normal. It ended about the 12th & the day after I experienced a really bad headache & severe nausea which ended with me vomiting multiple times. the day after that I encountered brown watery discharge like watery watery . So the day after that I took a pregnancy test& it came back negative. So I waited a week & throughout that week I experienced & am still experiencing symptoms (nausea dizziness headaches, horrible fatigue... etc.) I started to randomly get really tired and fall asleep randomly I have uncomfortable stomach pain and aches in my hips & lower back. I took another pregnancy test today and it is still negative. Could the plan b have not worked? & if I am pregnant am I testing too early? If not what else could this be?

Hello, Thanks for sharing your health concern with us. I have gone through the query and would like to offer some suggestions. Firstly, you do not need an emergency contraceptive if you have the intercourse during the safe period of your cycle. Ovulation occurs two weeks prior to the onset of the next period and this is the fertile phase of the cycle. Secondly, the high hormone content in the emergency contraceptive pill creates hormone imbalances and this is the most likely cause for your current symptoms. Since you have inconvenience, please get proper help from your health care provider. In the future, please restrict the use of the emergency contraceptive pill use for one or two occasions per year and go for regular contraception instead. Hope this helps.
