Absent period while on pill

Rachel

So I take Apri which is a combo pill, I took it before and always had no issues with it, always around the time I’m 3-4 days in of the white inactive pill I get my period. This time around that’s not the case I’m now still waiting for Aunt Flo and I’m bloated, tender breast and crampy but there is absolutely no sign of bleeding like I would normally get by now.. the pregnancy test I took was negative so idk anyone have this issue before???
