C-section with T-incision

Has anyone had the inverted T incision from their c section? If so, how long did you wait to get pregnant again?

I was told by most of the drs after my c section that I should wait 18 months, although a couple said to wait “at least 12 months”. I would like to start trying again ASAP, but just curious if there is actually much healing done between the 12-18 month period?

*Side note- I will be making an appt with my dr for my final decision- just curious about others experiences.
