Advice!

What can I do if I have a completely unplanned pregnancy and don’t have any idea how to manage this? Also what do I do if the man who did this is completely unresponsive, and toxic and I think could be in another relationship?

I’m pretty sure I don’t know where to start as the first step, any advice?

What should I do and how should I go about this? I am not sure yet but I have internal physical feelings happening?
