What do you think ladies? Is this a sign? Since 1DPO I've had extremely sore nipples they have become darken, bigger and very very sore. They started to leak colostrum (which has stopped now) at 1DPO, I breastfed my son for a year and it took me a long time for my milk to dry up. My breasts would still leak until maybe 2 years ago. The doctor said it was all good and everything is fine. My breasts are soooo veiny and I would say a cup size bigger. I'm shocked at this happening straight after ovulation I wasn't even symptom spotting but I can't help it now because of the leaking breast and extremely sore nipples. It feels like when your milk has just come through and you start breast feeding your baby for the first time.
