Sore breast but breastfeeding

Karissa

So my husband is deployed but he came back for ER leave for about 10 days. The last day he was here was 5 days before I O'ed (I think) and we BD'ed that day. I've had sore boobs for two days, which isn't normally a PMS symptom for me. AF is due tomorrow (7/10/17). Any moms who breastfed have sore boobs as an early pregnancy sign????
