I haven't had sex so I'm not worried about that. I think I could be Lactose intolerant so I dont know if that could be a play in it, I havent really beem stressed over anything unless you count a break up. I just dont want to have to talk to my mom if nothings really wrong. I think its been 20 days since I should have started? According to Glow but I used to not have a normal pattern so Im not sure if it can changed from time to time. I really dont want to talk with my mother as I'm not really comfortable with her and I avoid talking to her unless its serious.
