Good day, 2 days ago, my boyfriend and I had an unprotected sex. We were told by an OB friend that i should take contraceptive pills (4 pills within 12 hrs and then 4 pills again thereafter). I did as i was told. After taking the first dose, i felt dizzy and nauseous and It continued until the next day. Now, i noticed that i begin to develop rashes on my arms, neck and lower extremities and it is itchy. My legs also feel a little numb and it feels like there is lack of circulation in them. What could this be? Is this something serious? And also, i have fever, headache and muscle pain the day before the intercourse. I took paracetamol and ibuprofen. Does this play affect anything that im feeling right now? Thank you.
