to start things off, I'm not sexually active so I know I'm not pregnant

I was told to start lo loestrin fe on the first day of my period in May. once I did my period was probably over in two days compared to its typical 4 (although that doesn't show on the caldener because this app doesn't let the days vary...). then June came around and (sorry for the graphics) no period just discharge. now it's July and I'm supposed to be getting my period since I'll be on the second day of my placebo (I only have 2 placebo days) but all im getting is cramps. is this ok? I know like you usually have to get your period eventually or you get bloated correct ??? this will be my second missed period
