Don’t think I can handle this again

So after my son is born both hubby and I agreed to start trying again around the time he’s almost 2 or a little past 2 so there won’t be much of an age gap. (Honestly if we felt comfortable before then we’d probably try then) but I don’t think I can go through this again. The pregnancy symptoms don’t bother me, but the long wait for everything gets to me. I’m 20 weeks and already feel like I’ll never meet this little boy. It has felt like time has been dragging by so slow and I don’t know if I can take it a second time. It isn’t bad, but sitting and counting down days until things like the first ultrasound, the first gender ultrasound where you may or may not find out the gender, etc. it’s all mentally exhausting. I mean who knows maybe my son will make my life so eventful the time will fly by, but pregnancy drags by so slow. Every milestone seems like it takes years instead of months 😓
