So my boyfriend and I have been together for a little while and have sex very often. I got the <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> app and picked a period date approximate to what I remember being the last. Off of that estimate I have missed my period by a week. We don't use protection other than pull out. Both being seniors going off to college in a few months it is very stressful.. I had cramps a couple days ago and never got my period. Now I'm very sore down there. Very nervous but still too soon to take a test....😞 the pain down town could be totally separate but idk why I have that...
