I was fine with my first two as well - both were normal spontaneous labours with only ARM, but my third one was different. It was an induction after ARM failed to bring on contractions and I had a severe PPH at the end of it as well as a retained placenta. Once you have had a PPH, you are at a slightly higher risk of having another one, but I found after doing a bit of reading while pg with #4, that the risk of having a subsequent PPH was comparable to your 'apparent' risk of having one simply because you are having baby #4. So I wasn't terribly alarmed and knew that more than likely the PPH I did have was related more to the fact that I had an induction than any thing else. So come time to have baby 4 my midwife was prepared for it, but it never happened. I didn't have another PPH and bleeding was normal lochia. at 10 days PP I did pass a massive clot about tennis ball size and I had a bit of bleeding after that which stopped after an hour.
