New Pack of birth Control

Sheryl

I was off the pill for about 2 weeks (I just moved to a different state and didn’t know how to get my prescription info) I started the new pack in the middle of this month I’ve been on the pill now for about 2 1/2 weeks I think it’s been about three weeks now I woke up with cramps, nausea and very very light bleeding is this normal? Should I be concerned?
