Second pregnancy

So for my first pregnancy I was at I guess what some would call a normal weight. My husband and I are talking about trying for our own baby and I’m kind of nervous cause I’m overweight now and I worry I’ll gain a lot more and it’ll tank my confidence. Any advice? I know my husband thinks I’m beautiful and won’t care but I sure do. I like the cute pregnancy T-shirt’s and I worry

None will fit or you won’t be able to tell I’m pregnant. :(
