Anyone just found out there pregnant with there third?

This is completely unexpected and I have no clue what I’m going to do. My husband only wanted two and does not want ANY more. I’m on birth control, and just decided to take a test cause my period has been three days late. I got the faintest positive so I’m hoping it could be an evap line but I feel so extremely lost and dreading taking another one on friday. I need some words of encouragement. My oldest just turned 3 and obviously I’ll have a 1 year old at the end of this month. Idk if there’s any more love for me to go around. I feel horrible even saying that 😭 I’ve had such a hard time adjusting to two I can’t imagine a third.
