Hi I my cycles our irregular so I am not sure what is going on. I track my cycles so here are the last few months Jan. 7, March 6 and April 20 were the dates of the first date of my menstrual cycles they usually last 5 days. I took an early ovulation predictor on May 14 and it was positive I had sex with my husband between the 10th and the 12th we don't use protection. But ever since my ovulation my breasts have been extremely sore. This is not unusual because my breasts are usually sore for a week and then my period starts. My breasts have been sore longer than usual it's been probably 2 weeks now. It is not as sore as it was a few days ago now the pain is subsiding but my nipples are still very tender. I took a pregnancy test yesterday which can back negative. I am not sure what to do since my cycles are so irregular.
