Help with panic attacks!!

So I'm barely 6 weeks pregnant with my 3rd baby! I am very excited honestly for this baby, but I have covid and so I'm in quarantine along with my husband and my two babies (2&3) since last week (Thursday). I had been just fine, very bored and all but over all ok. Well since yesterday the panic attacks and anxiety won't leave me alone. I can't sleep with out having a full blown panic attack of screaming and crying. I feel like I'm going crazy and idk what yo do to stop them! I usually start counting when I feel a panic attack coming at me and it goes away but yesterday and today it's not working. Like I just can't stop it and it gets so bad. My husband is wonderful and helps me as much as he can to calm me and all but he says he's now worried. And I am too. I will mention to my doctor but that will be until next Wednesday. So from here till them can someone please tell me what you do to calm yourself a down?! How to you cope!? Any advice is welcome.
