Pregnant and paranoid or is this sketchy?

So- I'm fully willing to acknowledge that this might sound a little paranoid and crazy. Full disclosure, in our 10 years together I have never doubted my husbands faithfulness, wanted to search his phone's, gotten jealous, etc. I'm hoping this paranoia is just because I'm pregnant and hormonal and my self-esteem has been in the toilet but I thought it wouldn't hurt to get some outsiders perspectives. Back in the fall my husband was employed by a company that sent him on a lot of business trips. On one trip in particular he was sent with another woman (we will call her Brittany) to a different city in order to acquire a new organization. The entire time he was gone, he gushed on the phone to me about how amazing she was at data analysis and how he wished he had someone like her working for him. When they returned he mentioned to me that he was thinking about asking her supervisor if she could be placed under his program. Tbh I felt a little irritated by the amount he of time he spent talking about her and how much he was admiring her but I put it in perspective and reminded myself that if she was a guy, I wouldn't have a problem with it, and that I was probably being hormonal and jealous. Fast forward to present day- my husband took a new job in December and recently was given the go ahead to hire an assistant. We were running errands and his phone went off and he laughed when he read the text. I asked him what was funny and he said he had texted Brittany to tell her to apply for the job and she had just responded really excitedly at the opportunity. Again- I felt weird about it, and then felt weird that I felt weird. He mentioned tonight that he thinks shes perfect for the position but that hes going to take a couple more applicants so it doesn't look like hes just handing it to her and I immediately felt annoyed about it again. I dont really get my emotions in this because if he were talking about a Male peer, nothing he said would raise any red flags but for some reason I'm feeling totally sketched out by the situation. Any advice? I know I could talk to him about it directly but I honestly feel like I might be being crazy and dont really want to put that out there right now.
