Hi. I am a 22 years old girl. My periods were due on 11th September but got delayed, so I had homeopathic medicine, after which I got them on 18th September. They ended on 22nd and I had unprotected sex on 23rd. My partner did not ejaculate inside me, yet I took an I-pill just as a precaution on the next day. For the last 3-4 days I have been experiencing nausea and weakness and breakthrough bleeding has started today.
Is there anything to worry about? Will be periods be on time?
Also I have PCOD. Please help!

The I-pill have many side effects, (so do not take on regular basis) they are for emergency.

They can delay you period one or even two months. They can cause many other issues also.
They are also not 100 percent effective
