I stopped taking birth control a month ago. My boyfriend & I had unprotected sex twice a few days after last period.

The past few weeks I have been feeling:
Mild cramping.
Fatigue. Little to no energy.
Just recently I've started to have body aches (including back).
White, milky, odorless discharge. I've had this before, but not this frequent.
Frequent urination.

My period was supposed to start this week, but has not. I'm aware that the discontinuation of birth control could cause this.

I have NOT experienced any breast tenderness or soreness.
No spotting.
& only minor headaches, but that is nothing new to me.

I just want to know what's going on with my body. It's really uncomfortable. :(

Is it due to me stopping taking my birth control or could these be early pregnancy symptoms?
