Broody as anything but there's doubt

I'm so so so broody to be pregnant again. I would love to have children close together ( I have a 6 month old) but I'm in doubt of everyone rolling their eyes when I say I'm pregnant again so soon, and then the time off work etc. also I am so scared because everything went so perfect with my last that I'm scared it will all go so wrong this time. I really ideally would like go wait until my LO is 18months plus and I'm due to have the contraceptive implant fitted in October but as the date comes closer I can't help that feeling of regret. I want that excitement of seeing that BFP again because it's the best feeling in the world ❤ We are currently saving for a house and our goal is to buy one in 4 years time, so it just doesn't feel like the right time.
