Pregnant after miscarriage - questions

I *think* I might have finally, finally gotten my BFP (very faint line)!!

I had a miscarriage last year - aside from going in and getting bloodwork, what can I expect or ask for this time around to help it stick? Should I push for progesterone even if my levels are okay? Should I ask for weekly blood tests?

Not trying to be crazy, but I really want to do absolutely everything I can....

They already have me on baby aspirin.
