Help!!

I just had a chemical pregnancy on the 23rd of last month. With that pregnancy, my only symptoms were a missed period and increased urination. I never pee in the middle of the night. And last night and today I'm peeing like crazy! My period isn't due for a while now, and I'm just now in my fertile window. Is it too soon to be pregnant already and already having increased urination? I feel like I'm going crazy.
