How do I tell the dad that I’m pregnant

kchels

I’m superrrr early (only 4w2d) but I have a 10 month old daughter me and her father split in June but I’m now pregnant (by him) again . I want the baby. I’m not sure how he feels but he didn’t seem concerned when he’d come over and not use protection 🤷🏻‍♀️. Just not sure how I approach the situation
