First time using BC pill

Veronica

I just got prescribed yesterday and started taking it right away, I got my period a week ago that only ended a few days ago, my doc said I would be fine taking it whenever.

I am wondering if it’s normal to have period like symptoms after only taking one pill? I feel like I’m getting the same cramps I usually feel during my period and I also feel slightly more nauseas than usually do on my p. Is it the bc or am I just experiencing a normal stomach ache? I also keep having to run to the bathroom to 💩, which is also more frequent on my period. I just think it’s strange and maybe a coincidence that i feel so bleh.
