I'm on blood thinners & I just found out I'm pregnant.

I have Pulmonary Emboli and I'm taking Xeralto  and just found out I'm pregnant, this will be my second child. I've never been on blood thinners before, online it says it's category C which I guess means they can't rule out any birth defects? I'm still nervous I haven't been to the doctor yet. I'm going next week. Or should I go sooner?
