To tell or not to tell?

I'm sorry ladies I just had to vent. I'm pregnant with my 4th child and I haven't told anyone but my husband and one of his cousin's since his gf is pregnant too. Anyways im afraid to tell my family and his because I'm 21 and I'm on my 4th child. But I don't work all I ever wanted to be was a mommy and I get to be home all day bathing and feeding and enjoying life with my little miracles but they don't see it that way they see it as I'm too young to handle my kids which I'm not. This is the only time in my life I'm happy is with my babies and my husband. And my husband nice of him wants to make a baby shower for our last baby in at least 6-10 more years, but I feel embarrassed by the bad looks and rejection or gossip my little family is gonna get. The only one loving me for who I am is my dad. He's in jail but hes the only one with me always. Idk what to do.
