Period still not here almost 4 months later

I have been cramping these past few months and no period whatsoever. I spotted this month and I thought that maybe these month would be the month to get my period, I feel disappointed. Yesterday one of fb friends announced her pregnancy, I told my fiance and what he said sounded like he was disappointed, he said everyone is getting pregnant, I know we have to give it time but its disappointing to see everyone get pregnant and us not even get my period to start trying.😭😭😭
