How are the effects of birth control mentally and physically?

I know it’s diff for everyone and this will be my first time going on it!

Mentally does it..

Make you sad?

Cry for a lil sometimes randomly?

Physically did it..

Make your period cramps better?

More or less discharge?

Gain more weight?

Regulate your period?

Make you stop throwing up on your period? (I have this, one reason I am on it!)

Make your pussy a little more dryer?

Also if you gained weight did it help to go to the gym? Or did you stay the same because of the birth control?

All help is appreciated ❤️❤️
