We have been trying for a baby for a while now after a miscarriage. This month, my breasts really started to swell and ache about 3 days after ovulation. As we had sex pre-ovulation and my breasts do not usually ache during my cycle, I thought it might be pregnant. But about 3 days after the aching started, I woke up one morning to find that the pain had started to ease. About a week later my breasts are completely back to normal. I am due to have my period in the next few days. Has anyone had this experience before? Have I miscarried?
