Husband doesn’t believe I’m pregnant

So I’ve had issues getting pregnant in the past with my ex husband. We never ended up having a baby. I could get pregnant but I could never stay pregnant between miscarriages and an ectopic pregnancy.

When I started trying with my now husband he knew my history and he blamed it on my ex. ( I never got fertility testing) we got pregnant on the first try and I had my first living child in November 2023. No complications, no scares. Just a healthy baby and healthy pregnancy.

I got pregnant again in May and I miscarried in June. It hit hard and all the past losses came flooding back to me….that was the first time my husband has ever dealt with a miscarriage…I’m now pregnant again the cycle after that loss and he’s saying I’m not really pregnant until he sees a heartbeat….i understand maybe it’s his way of protecting himself from more disappointment or heartbreak but I need support especially in the beginning days of pregnancy and I feel like he’s dismissing me and he’s saying I shouldn’t be testing so early and that he is not acknowledging it until 8 weeks or an ultrasound confirms it. I told him it doesn’t matter when I test if I’m pregnant then I’m pregnant….im also 4weeks 1day. So I’m not even testing like a week early or anything like I have before. I got a positive digital and two positive line tests and I’ve stopped testing.

What can I say to him to make him understand that I wouldn’t get a positive digital test if I wasn’t pregnant and that right now is when I need him the most. I just feel heartbroken and like he doesn’t believe that I’m pregnant.
