I had similar side effects as you, swollen stomach, bloatedness and pain during sx but it wasnt unbearable. As rjoshua says, everyone responds diferently and I agree that if its bad, go to ER.
Good luck!

What were your side affects?
I've taken these shots and have never experienced this, but every women's body reponds differently to medication.
If you continue to feel discomfort I would go to the ER. Rather safe then sorry.
Hope this helps.
