birth control side effects?

Megan
I'm having such a hard time right now. I took my first ever birth control pill last night. My period was almost over,
This morning I woke up feeling sick and felt awful at work until I ate something small. I eventually felt sick again after work. My
Stomach has been so bloated and feeling full even though I've barely eaten, and now I'm having spotting again even though my period was almost over. I also feel unusually cold.
What's wrong with me? Are these typical side effects?
