not feeling touchy since pregnant

Ever since found out pregnant I lost my interest in sex or being cuddly cuz I feel so conscious of my body cuz I feel so fat. Husband is sweet tho he never asked for it cuz I always complain I have morning sickness and boobs sore and tender. He's so patient and kind with me. When I admitted is cause I haven't been feeling it he is also very sweet about it. But in the end he is still my husband I don't want to restrict him just because I'm pregnant. Is this normal? What can I do to gain my confidence back during pregnancy. I only in first trimester but already gained weight.
