When its your first month on pills, I always heard that you need to use a condom due for the fact that it takes a month for pills to actually start doing there job

Whoops : / I feel like im about to have my period but this is my first week and a half on the pill.....

Thats exactly what you feel like when you start the pill.
It mimics pregnancy.
The side affects should calm down soon, and you'll feel better.

If you really think you are pregnant, the pill will not affect a hpt, so you could test if you like.
