A newbie

Hi im 21 years old and im new to the whole pill thing. Yesterday was my first time taking the morning after pill after having sex for the first time the next day i woke up and it looks like I got my period which is 2 weeks early, is this normal?

Also how common is it for women to gain weight while using the pill in general? And if i wanna get on the pill do I take it daily? Will it affect my college life?

Thank you in advance for everyone answering my questions ❤️❤️
