How many maternity pads? 🇬🇧

Sam • 🇬🇧 UK Full Time Mum, 2YO girl, pregnant with 2nd

Just wondering how many I will need, I've bought 4 packs of 10 maternity pads (the thick ones from Superdrug) and 2 packs of 10 Always sensitive nights.

Will I need more than that?? I know some people say they bleed for 6 weeks! 😱
