Had dd4 25 days ago, lochia had tailed off and stopped as usual by middle of week 2. Last week I had a bit of spotting one day but thought nothing of it. However, by Sunday I had started bleeding again and it has got heavier. Definitely not sex related as DH away with work! And I didn't get my periods back until after 9 months with the other 3 as they are all exclusively bf. This baby is the same, still feeding at night etc so surely can't be that? Should I be worried or is this just one of those things?
