Pregnant with #4

I been waiting on my period so today I finally decided to do 2 home tests that came back positive. Told my husband and he shocked but he wants me to do a abortion and that’s something I’m against Idk how to even feel right now we got 3 already 2 boys(8&4) & 1 girl(2) ...He scared of what others going to say since we 24 it’s just I can’t abort one and we never said that with the others... just feeling depressed right now over it all
