AF showed up today and I’m heart broken need support please

Didn’t think I would be this emotional about my period. First month TTC with husband, Mirena out last month and all the ppl at the clinic said it would happen right away so I guess I got my hopes up. Now I feel like there must be something wrong with me bc my husband and I have sex everyday, multiple times a day usually. I know it’s early and I know everyone is gonna say I’m being ridiculous but I feel so upset I’m sick. Like I got punched in the stomach and can’t get air. Please please help. I’m worried I can’t get pregnant or something bc I’ve never TTC before so idk.
