Too soon?

Was looking for any advice or suggestions!

Hey guys! My husband and I have already been blessed with three beautiful little babies and are thinking of trying for our last baby soon. All of my children have very close ages gaps ( 3yrs, 18 months, 4 months) and we’d like to have an age gap of about 18 months with our final baby and our youngest. I had an emergency C-section in May of this year and after testing my placenta and doing a variety of tests on my son and I they have found no reason for the cause. My son has been perfectly healthy since delivery and thankfully has had no complications even though his delivery was a month early. After some conversations my husband and I have decided we would like to try and have one more baby and ideally sooner rather than later. I am just curious on y’all’s recommendations or advice on this situation given my C-section. Is it safe to try for a baby around 9 months postpartum? Have any of yall had any complications with getting pregnant too soon? I have an appointment with my OB at the end of this month but was curious to hear from the glow community! Thank you!
