Advice ASAP telling hubby I’m pregnant again after miscarriage

I had Miscarriage on Feb 16 . The pregnancy wasn’t planned but it was not avoided but when I found out I was expecting I suprised my fiancé with a valentine gift 🎁 telling him he be dad again . He was happy but scared since I graduate in July from college with a radiologic technologist degree and we have a 13 month old. He does have a good job that can support another child but he would prefer to live in house prior to our next child. I been nasuea for two days now . I took a test and got three positive and one negative from clear blue ( because i think HCG is to low) . I’m happy and scared to be pregnant because I don’t know how to handle a nother miscarriage. So my question is to you guys how to tell your significant other that your pregnant again after a miscarriage? He didn’t want another one since we lost the other one but again we didn’t protect which is hard to understand him sometime . He rarely talk about our angel above. I asked if he was ok and he would say yes . But I feel he wasn’t just trying to be strong. I don’t know how to bring this to him . Any advice would help ?
