A little Nervous Now

I am currently on cycle day 94 😨 when I realized I missed my period I wasn’t worried thinking late is normal sometimes but now I’m kind of a nervous I’m 15 yrs old and I live with my Dad because my parents got divorced. I’m really bloated before and after eating even when I wake up. I haven’t experience any cramping yet which I know means my period will come but nothing and my Dad asked me about my stomach I told him I was gaining weight and he jokingly said “sheesh thank God because I would of been really upset”😢 yes I have had sex in the past 😔 with my very first boyfriend and he didn’t wanna use a condom but I went along with it because well I didn’t wanna lose him. Now I’m regretting it but love him so much.
