I feel like I'm going crazy, I have a gut feeling my SO is lying to me about something, or hiding something from me

So the past 2 weeks or so

Hes turned off his notifications from snapchat and facebook messenger - he said the constant notifications were bothering him

He has admitted to deleting texts before I see them - his friends send him really gross cringy things - makes me feel like what else is he deleting?

Hes been dressing up good to to to work the past 2 days - it feels like hes trying to impress someone, he says I'm crazy

I'm getting bloodwork every 2 weeks to monitor hormones to make sure I dont have cancer, I had an appointment on friday, hes known for 2 weeks about it, and needs to watch our daughter, but he fought me tooth and nail about it suddenly one day, he wants to work overtime on that day, it was the only time I could get bloodwork done in weeks (all booked up), there was no other place I could go, we had a huge argument about it, he wanted me to put off my appointment to find out if I have cancer so he could work an extra day, and he wouldn't let up. My only option was to get it done last minute that day, if he got off work early. So that's what he did, he got off early.

Btw we just moved to this city, and dont know anyone, and theres a lot of covid cases here.

I feel like he doesnt care about my wellbeing, it was only important to me.

I also caught him in a lie, a very tiny lie, so minuscule, but it bothered me, I couldn't understand why he would lie about it. Me mentioning it sparked an argument, which tumbled into a bunch of other things, like what I mentioned above. I accused him of lying to me about other things, and his response was to delete snapchat, but our argument had nothing to do with snapchat, besides he turned off his notifications for his messaging apps. Makes me feel like hes feeling guilty for what hes doing on snapchat if that was his only solution to all this

I cant tell if I'm being the hormonal crazy one, or if I have a right to be suspicious of him

Btw I just had a miscarriage and my hormones are out of whack, that on top of my crazy hormones that are being monitored for potential cancer.

Advice please
