Not sure what’s happening

Back story: i miscarried in September.

Me and my husband aren’t technically TTC but we aren’t preventing either.

My period is pretty irregular and I’m currently 4-5 days late. Should i test? Or should i give it a few more days since my period is pretty irregular?

We had sex 3 or 4 times during my last ovulation one of the days being my highest chance day.

Not really sure what i should do. I feel fine no symptoms other than acne, tender breast etc (normal period signs)

I am skeptical about testing after the miscarriage so I’m kinda torn.

TIA!!
