I haven't had a period since Feb 7th 2017. I got real sick march 7th, I started throwing up outta no where. I have a <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period calendar</a> to keep track of my period seems it's always been irregular. But since august 2016 I have gotten a period every month. I'm having strong cramp In my lower belly and I can feel them in my Back. #Help haven't tooken any test yet as in results to a late irregular period. This happen to anyone else?
