Im not quite sure if im regular or irregular. Sometimes my period comes every month and then sometimes it comes like 2 months later so im not sure what i am exactly?? Last month i got my period somewhere around the teens and i think i was supposed to get it on the 16th this month according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a>. I had sex almost a month ago with condom but i dont have no pregnancy symptoms at all. I just need help right now im worried. Also my stomach is hurting right now can it  be just cramps?? ):
