Getting Pregnant 4 months PP….

My son is just about 4 months old, and although my labor and delivery was so horrible (emergency c-section, lots of complications) and I swore I’d be one-and-done…….I just ordered ovulation and pregnancy tests to start TTCing again LOL. Getting pregnant with my son took a long time and TTC was such a huge part of my life I kind of miss all the tracking and I’m worried its going to take a long time again for baby #2. Anyone else have babies super close in age? Am I crazy? Haha
