When to test?

Hello Everyone! I’m new to the group and just need some advice. It’s currently been 46 days since the start of my last period. I started my period on January 17 and ended on January 21. I do have irregular periods. I’d normally say it’s about a 30 day cycle.

I’ve had unprotected sex in between then and now. In the earlier weeks I did have some cramping which led me to believe I was going to start but never did. I’ve been getting nauseous and feeling like I was going to throw up but haven’t physically thrown up yet.

I’m nervous to take a test but wanted to get advice on whether I should take a test or just wait.
