Not me personally but I have nursed lots of people who have and more. The most been 7 over 13years. The ladies first 5 were uneventful but complications for number 6 and 7 due to the amount of scarring. As a midwife I can't remember caring for anyone that encountered problems with their 4th but 1st and 2nd and if you have had a normal recovery with the last 3 I can't see why no4 would be different. Alot of women have their tubes tided with the 4th at Drs advise but many dont and Ive seen plenty of women go on to have more then 4 c/s. Good luck with it all.
