When I Quit Birth Control

I've been off birth control for about 4 weeks now and I thought I would share with you what kind of changes I have noticed so far coming off of it!  Note that I had been on birth control for 8 years
My body (mostly my face) has become way more oily
I've gotten a few extra pimples, but they aren't in the usual spots, they're in places I never had them before (above my eyebrow, right under my eye, and one my neck!)
I get nauseous more often.
I have random dull period pains at night sometimes for some reason. 
Now all of these symptoms are what I was like before going on birth control so it isn't surprising, but I had forgotten that I use to be like this previously. 
I haven't had my period yet so I don't know how it is going to be but I anticipate it to be just as painful and heavy as it use to be. :(
