Is this normal?

So last night I noticed my nipples have little to no feeling. They don’t hurt and I can’t really feel anything from them when I touch them, I pinched them to try to see if that would cause some pain and I still didn’t really feel it. I am making a ton of colostrum tho And have noticed that my boobs are becoming vainy and engorged so I think my milk make be starting to come in or something. Has anyone experienced this or is it normal? I’m a first time mom so I’m really new to all this stuff.

I’m 30 weeks pregnant
