mixed feelings getting Pregnant after MC?

I'm getting nervous about how I am feeling. my husband got our very first BFP in February this year and had an MC early March. It was devastating as we had been TTC with PCOS for 1 year. well my period came and we tried again with my fetility meds and my TWW is up on Sunday. Before, I was so nervous, excited, and antsy to test. I would ALWAYS test early and it would be all I thought about during the TWW, constantly googling early symptoms, over analyzing everything, looking at baby names, clothes etc.

This time around it's so much different. I'm scared for it to be positive because I don't want to lose another. is this normal? did we start TTC to early after a MC or do these feeling happen regardless of how long you wait just because it is now in you mind that you could very well lose another?

I just want this to be exciting for us but I'm starting to think that those feelings only happen to those who have no pregnancy issues and get pregnant naturally.

Anyone else? Your tips and advice would be greatly appreciated.
