Am I doing something wrong?

Me and my S. O have been together for 7 months, before we got together he knew i was pregnant with previous partner and lost it at 5 weeks, he also knows a lot about my past and the unfortunate situations and circumstances I've had to deal with.

I feel like every time any of there things such as pregnancy or having children as well as (bad) past relationships (which i would say I've been there and lived through it) come up he makes a weird face or makes a comment that makes me feel like I shouldn't be bringing up the past but also I thing he forgets that im a very opinionated person, who has been through a lot and if I can give advice or at least share my experience to help someone im all for it.

However I feel like my partner hates that I still can remember my life before him?

I'm not sure that's the case, that's just the way I feel, I just wanted an outsiders point of view before I bring it woth him.
