First time using the morning after pill

So to cut a long story short, I am seeking some advice or guidance as this is a first time thing for me. We had unprotected sex and took the morning after pill the next day, since then I have been experiencing mild headaches and cramps, sore nipples that have changed appearance slightly as well as my breasts I think too. Feeling nauseous all the time but really hungry.

Struggle to sleep as well.. took the pill when I was already in ovulation, and have taken an ovulation test every day. The first day I took the pill the test had very dark lines, every day after that has been very faded to now almost not visible. I know the symptoms from the pill is supposed to be almost the same to your period but I do not actually get these symptoms when approaching mine it kinda just shows up. I am still a week and a half out from getting mine. I am currently 5dpo, what can I be expecting to see & when will my body feel normal again?

Thanks!
