Pregnancy Scare

My fiancé thinks i’m pregnant because i sleep 24/7 my face is breaking out i eat a lot of junk food im very moody plus my period has not came on in about 2 months and i’ve gain a few pounds but i’ve been to the clinic and i’ve taken a home pregnancy test and they all came out negative.. btw we haven’t had sex since like october ( he works and i have school ) i think if i was pregnant i would know by now but what do you guys think ?? 🤔
