Is something wrong with me 😢😔

Okay ladies, I’m in desperate help and motivation 😅😅😅 I haven’t had sex since June and my cycle has been pretty consistent and normal lately. Well for this month, I was supposed to have my period on the 9, and currently I am 13 days late....no sex no nothing. I have been losing weight and now I think I gained a few pounds back. I have felt nauseas, hormonal, binge eating like crazyyyyyyyyyy. Help me because idk why I’m so late and what’s going on!
