Sad feeling alone and confused

I just found out I am pregnant while my boyfriend was on a flight back home to visit his children and mom and grandma. I told him as soon as he landed and we haven’t talked about it at all since finding out. Prior to this 2 week trip we had a conversation about hypothetically being pregnant and what the plan would be. But to know that I am and not have a single conversation about it I do not like the feelings it is making me feel. I am unsure and it’s giving me so much anxiety and causing me to have the most horrific nightmares of my life. I can’t wait for him to get back so I can have some sort of reassurance that he is in this with me and everything will be ok. I think I’m just letting the hormones take over and making me overthink but idk.
