My periods are pretty much regular.I always get my periods between 26th to 29th day. I feel soreness, heaviness and pain in my breast from 17th/18th day, but this time I am not feeling any soreness or heaviness or pain in my breast till now.My last period date was 11th Aug and today is the 25th day of my cycle. Me and my husband are ttc since last 9 months after my ectopic pregnancy surgery in july last year 2016. I am bit confused this time. Please help me in clearing my confusion.
