How to tell husband?

Meg

We did spontaneous sex randomly in our closet to hide from the kids cuz it had been months since any intimacy. He pulled outish I immediately went into the shower and washed. Well when period is approaching I noticed odd cramping and lower back pain with discharge I know this feeling all too well and don’t need a test to tell me there is a lil baby brewing downstairs. We have 3 kids and got the girl he said he was done but life has other priorities in tow I couldn’t even get to the gyno to get more bc they denied my refill cuz a Pap smear I mean my money was more important than prevention that too I’m happy I just honestly don’t know when is the right time to tell him and how well he will take the news should I wait after the first appointment or now
