So I should of gotten my period two days ago and didn't. It is never late! I have an app on my phone that tells me when it is coming and it has never been wrong yet and I've used it for 8 months now. So- the day before I should of started I had cramping which is normal before my period. But then it never came. Since then I had zero symptoms that I would normally have. I took two home pregnancy test that said negative. Now I appear to be spotting a tiny tiny bit. I'd like to know if my period is coming or if I'm pregnant. I'm going out of town in 3 days and don't want to be doing any activities I shouldn't be (roller coasters, drinking, etc.) if I am expecting. So I don't know what to do now. Any advice??
