Need Advice.

I am 3 days away from AF. Since my kids I don’t have cramps anymore but yesterday I had some random cramps for about an hour or so. I’m also tired oddly hungry and moody which could all be PMS too - I am just starting thing it may be early pregnancy. I have 2 kids but symptoms were both so different and I honestly just forget 😅 my husband and I were on vacation when I was ovulating and were kind of careful lol my cycle has also gotten shorter since kids bc right now I’m only 12 DPO so I’m confused if I would get a positive test right now.
