Can I jump in here?

I'm struggling to find somewhere that I fit.
I'm 4 weeks pregnant with #2 after 22 months TTC, fell pregnant on my 3rd IVF cycle after cycle 2 resulted in a chemical pregnancy.

I'm finding it hard to recognize pregnancy symptoms, vs the progesterone side effects.
I'm so paranoid that I'll have a miscarriage and not know because progesterone will stop me from bleeding.

I'm just really scared
