I am 1 day late into my period going on 2 tomorrow which I’ve never been late on my period ever! So I’m really scared , I don’t know if I should take a test or not ... I’m thinking I should hold it out a lil longer my friend told me to download this app I haven’t missed a period until I downloaded this app so I’m believing it but I’m a little questionable on how accurate this app is !? Answers pleaseeeeeee !!!
