To reach out or not

Sooo husband has been acting a little weird and I started getting insecure...randomly checked his phone calls and one number repeatedly came up, googled the number and came to find out it’s an escort service number. The girls ad is on a few different webpages. Needless to say all texts have been deleted so I don’t know what exactly the situation is.

I know talking to my husband will just lead to him denying it and say it was accidental calls or he didn’t act on anything.

I have a number, should I reach out to the number and ask to verify if my husband has visited there or not?? Do you think she will care for a plea from a 7 month pregnant woman to verify if my husband is cheating on me? I’m torn.
