Missed bc and he don't know

Kendre
So I have been with my SO for 5 months he has two girls 7 and 4 he doesn't want to have a baby for a while he wants us to be able to enjoy our self as a couple, so I am on the pill but I can't ever remember to take it and he thinks I take it every day. Now I am two days late and afraid to take a test because I am afraid he is going to be upset and I am afraid to tell him that I never remember to take the pill.. He is the most amazing man and father I would love to have a baby with him but don't know what I should do any advice???
