Should i be worried?

We are 12 years together, 5 married. We have 2 kids, 3rd on the way. He works, i dont, he have his own team on his work and in that team there are few girls. Like our ages. From time to time he talks to me about them, and from that stories, like there is no way he could do anything with any of that girls. But in a last few weeks, he starts talking like, they told him some nice words, like how he is hardworking, trying to buy him a coffee, and stuff like that. Last night, he was looking for lip-salve, and i just bought one, and gave him, and told him, yeah you should take it, i see your lips are dry (winter is here, happens every year). And he told me- i know J (co-worker, one of girls) told me that also, today.

I didnt realise it at the moment, after few minutes i got what he said. Wtf? You have to be pretty close to someone to see their lips, right? Isnt that too much intimate thing to say to someone, who you just work with??

I am pregnant, maybe i am overreacting.

Edit: actualy not an update, but i just realise that my husband is getting shower every time before work.

He is on high position in his company, i understand he wants to give people nice impesssion of him.

I didnt find out anything else that is turning alarm. He is really nice, always helping everyone he can. I guess i dont have to worry, but i will be carefull. Thank you for answers, you are all very nice.
