So I've been using another app called Ovia that I heard great reviews on. I've been using it for over a month so things have made sure to sync up correctly. It said that I was supposed to start my period on the 19th and when I didn't start I entered that and it said to take a test and it naturally shifted to say it might start Sunday the 21st. The test was negative. I haven't started yet and when I enter "no period" it's not recalculating my period. It's saying there's only two more days that I might have one. Does this mean I'm actually late now? I wanna take a test but am nervous. I only have 1 test left that's the cheap .99 assured brand from dollar general. It also keeps telling me based on my symptoms lately that they could be either early pregnancy signs or period signs but..no period yet. My ovulation week was from 5/2-5/9.
