scared

Hey girls.
I posted on here a month ago concerning my missing period. I have still not gotten it (107 days late) and have taken 3 pregnancy tests that all came out negative. I am 20 y/o. I have an OB appointment next week but I am so very scared as to what is going on. I have so many pregnancy symptoms but no positive tests and the area around my ovaries has had a lot of pressure. Have any of you have this kind of issue??? Please respond I just need moral support. & before anyone says anything, the doctors typically wait until you haven't had your period for 3 months before they tell you they really need to see you, so that is what I did. Please give a girl some insight 💜💜💜
