Hi, I am 29yrs old experiencing very sore breast, dizziness, fatigue, and nausea for the past 2-3 weeks and my cycle isn t due for another 10-12 days. I took a home pregnancy test which was negative, is there any explanation as to why I am experiencing these symptoms? A little history about me is that I have one 8yr old by cesarean and an ectopic pregnancy about a great ago.
