I just wanna give up ...

My fiancé and I are both 19, we’ve been sleeping together unprotected for about 8 months.. and have yet to get pregnant. I’m 3 days late today and thought maybe this was it. When I went and wiped just now there was really light pink on the TP... how is it this difficult 😭 I decided a month ago “I didn’t want kids rn” because I didn’t wanna keep getting my hopes up. But this just has me sobbing.
