Hello, this is my first time writing on one of these, but its been awhile and I feel like some feedback from other women would really help me either calm my nerves or help me decide what I need to be worried about. I am 20 years old, and I have been dating my boyfriend for 2 years now. We have always used condoms during intercourse, but my period has always been irregular. I have tried scheduling or trying to predict my period for him so we do not worry, but its always 2-4 says late, and its been that way since I can remember. My last period was two days early on April 25th, and on my little period app I was suppose to start May 23rd. but when I did not start 4 days later, I took two tests:negative. I waited two days, and took two more tests:negative. My boyfriend and I think it might be because the two weeks before I was extremely stressed, and I was. I broke down almost twice everyday. So I waited another week and when I was 9 days late I took two more tests:negative. My abdomen area is hurting a little but its not a sharp pain, and it ranges from my stomach to just below my bellybutton. I am having clear discharge but i have always had that. 

I am sorry this is so long, i just want to give everything for the most help. I want to think I am not pregnant, and that its just stress that has caused my period to skip or something is medically wrong. Any feedback would help so much, anything.
