Yes, I am pregnant now (6 weeks) and still awaiting results to see if I am pregnant with multiples or have a molar pregnancy since my hcg levels were quadrupling every 3 days. Breastfeeding increases your chances 9 fold of having multiples. And yes, now that you mention it, my nipples ARE sore. I thought it was because my son keeps pinching them or maybe is being more rough in eating because he's teething, but maybe it's because I am pregnant. And they seems drier.
yes i got pregnant 3 times while breastfeeding and the second time the child i lost i have very sore nipples that were cracked really badly
