Husband not wanting another baby....

Okay... Between my husband and I we have a daughter and a daughter from previous relationship. We got pregnant at second time this year and ended in a miscarriage. I mc in October. I told him I wanted a baby just not anytime soon. The mc was heart breaking and so hard on both of us it made him not want any more. Which kinda scared me for the simple fact that we don't use anything and I'm not on birth control I've taken test after test after test this past week and a half and they all come out positive and dark heavy lines the last 3 test I've taken. I'm not sure how to tell him cause he has repeatedly told him he doesn't wanna go through another lose. I don't want the pregnancy to tear us apart either. The app says I'm around six weeks. I need advice..no judgement please. I'm lost and dont know what to do.

Posting anonymously cause I don't want people I know knowing.

UPDATE: I miscarried at 14 weeks. Went to the Dr and there was no heartbeat I was supposed to be 16 weeks at my appt but there was no heart beat. I know there's always a possibility of mc or still birth all through pregnancy and he knows that too. Thank you for the advice so far. I'm not quiet sure when to or how to. I have an appt the 28th next week

UPDATE: Thank you ladies for your advice. I have decided that I am going to tell him after we pass the 14 weeks when I mc our last child. If I don't show by then can't hide it forever. Again thank you ladies.
