Nervous the ask my husband to start trying😥

My husband and I have a great relationship. He genuinely is my best friend. Usually we talk about everything under the sun, no topics are ever off limits. We just moved into a house last year and I just purchased our first family car. I figured once we were all settled we'd start trying... like that was a plan we talked about awhile go...but its been months and my husband hasn't said a single thing.....

I dont know how to bring the topic up because I'm 30 and I'm at the point right now that if he says we should wait.... I might cry and almost feel hurt by it.

Any advice on how I can start the conversation
