Breastfeeding

Based on this article (http://www.theglobeandmail.com/life/health-and-fitness/health/is-it-safe-to-take-vitamins-after-the-expiry-date/article29218751/), it will not harm you to take the expired vitamin. However, the potency of the multivitamin will be lost and will likely lose its effectiveness. The article did mention that potency drop-off for vitamins is slow. As such, one to three months past expiry date should not be too far off from the original nutrient content, especially if the multivitamin is stored properly (following the storing instructions stated). In all, there will not be any harmful effect on you if you choose to take it, but definitely will not be getting the same amount as stated on the label.

According to this article (http://sg.theasianparent.com/lochia_postpartum_bleeding_singapore/), Lochia will change from bright red, to pale brown and finally to yellowish white. While it typically stop one month after delivery, for some ladies, it could last till 8 weeks. Not sure if this is the same discharge that you have noticed. I doubt you are pregnant again since you are breastfeeding on demand. Though other factors may affect how soon the period returns. From what I've read, breastfeeding is likely to be effective in delaying the menstruation cycle for at least the first 9 weeks (for more information, you can refer to this article: http://www.healthline.com/health/pregnancy/how-soon-can-you-get-pregnant-after-baby#2). There may be other causes to your nauseousness. Perhaps you would like to see a doctor just to be sure? Take care mummy!!
