My MW has said to take 1 when labour starts, 1 at start of second stage, 1 1 hour after delivery and then next 3 days 1 tablet 3 times a day. For a C section take 1 tablet 3 times a day the day before, 1 tablet just before the op, 1 tablet within an hour of op then 1 tablet 3 times a day for 3 days. The MW also mentioned Hypericumis to help with the pain of the healing scar after c section, this can be taken with arnica.
