Thought I was pregnant

So my period was over 2 weeks late and I was sure I had a positive pregnancy test last week but all after that were negative. At first I was freaking out as I wasn’t TTC yet but after talking to my OT and family I started getting excited. AF finally started today so I know I’m not pregnant but now I’m so excited to start trying. I wanted to wait until after Christmas but now I’m think of TTC when my baby boy is 14months(we have a holiday booked so after that). It took us almost 1 year to get pregnant the first time so I’m happy to start trying sooner rather than later! What age gaps do you think are best between babies? When are you planning to TTC again? 💖
