When is it okay to get excited? ( trigger warning hpt)

My due date for my angel baby was the 5th of this month, I just got these two tests today. I’m scared to get excited.

How long does it take for a chemical to happen, when do I know I’m in the clear.

I have an appointment the 24th that was a follow up to see if I needed medication to help us conceive again. Can I tell them I want progesterone? How often can I get them to test my progesterone?

So many thoughts, I want to get excited but god it’s so scary!!
