Pregnant & have a 6 month old.

Any of you mommy’s pregnant and also have a baby under 1 year? I just found out Friday that I’m pregnant again. Not sure how far along because I haven’t started my period back since giving birth to my daughter 6 months ago. I was on birth control but we weren’t using any other kind of protection. We definitely didn’t plan it. I haven’t even told my husband yet because I’m nervous to how he’s going to react. I guess I’m just looking for some advice. Or maybe someone to talk to that’s in a similar situation.
