Need to vent

Any advice or coping mechanisms would be appreciated! Please no negative comments.

Here’s a little background of me and my life at the moment. I’m 22 and it’s my last year at community college before I transfer to a university, I have two jobs & school is full time. Me and my bf have been together for over 2 years & were both madly in love with each other & have a great relationship. We do want children and to get married eventually. Wellll.. So for the last month I just had this feeling in my soul that I was pregnant. I was 3 weeks late, I was nauseous, extra tired(more than usual), & very emotional. I took multiple pregnancy tests and a few came out with 2 lines (one very faint) so I made a doctors appointment just to make sure. Well literally the night before my appointment I started my period. I was relieved (bc I’m still in school) but I was also very sad about it too and never even realized how bad I wanted a baby until that moment. I guess I had just mentally prepared myself & was so convinced I was :/ has anyone else ever felt this way? And yes i do know I’m still young and I have school id like to finish before becoming pregnant, but it doesn’t change that im still overwhelmingly sad about it :( and no I’m not trying at all, I’m on birth control pills but I did miss two days & my bf did not pull out on time which was why I knew there was a possibility.
