Unexpected Pregnancy

Twenty-two years after the birth of my son I am pregnant once again. I'm not with the father and he doesnt have the best history with his existing children...nor did he have a positive or even humanistic response when I told him.

Backstory, I am recently divorced and finally back on the dating scene when this happened. I have had extremely regular cycles my whole life but periods had been off by a day or so these past couple months ... to the point where my doctor had been testing me for and recommending pre-menopause treatments.

Anyways, just wondering if anyone out there has any sage advice or have gone through anything similar.
