Should I take a test?

I saw two pregnant women yesterday and had a dream about a baby last night. I've been cramping and showing a lot of CM lately. My boyfriend had a vesectomy. But there's always a chance right? But I am hoping to have another without the reversal. I have been having headaches and some cravings lately. Should I take a test or am I just imagining this all? Oh and I'm cramping. Had my period two weeks ago about.
