is this from birthcontrol?

a • wife & mommy!❣️

i just started taking birthcontrol last week the day my period started and ever since i took the birthcontrol i’ve been having little discharge that has had blood streaks in it.. well today i went to pee and i noticed blood on my panties so i wiped and saw this... has this happened to anyone before? also my smell has been off and my nipples have been sore and i’ve had some diarrhea..
