Caught by surprise

Hello all! My recent pregnancy news definitely caught me and my fiancé by surprise!  I always envisioned us having kids but not until a little later. We have been together for a very long time and are both of an age where it makes sense, but weren't yet trying for a baby. I feel like it must be meant to be and am trying to look ahead with excitement, but am feeling super freaked out and a little scared. I'm hoping I'm not the only one feeling this way! Thanks in advance for the support!
