Iron and calcium supplements

14mos post partum FTM Direct breastfeeding from start Last month I got my period na and since then pakiramdam ko parang naging mas light-headed ako. Mothering plus duties sa bahay kaya siguro ganun. Gusto ko sanang manumbalik sa iron. I took iron supplements only on the 1st month post partum. Ask ko lang po if okay lang ba uminom ulit ako ng mga otc na iron and calcium supplements? Currently ito po ang inintake ko ascorbic acid, multivitamins and an adult milk. Thank you po.
