I've given up trying to figure out my body i have lower back pain, abdominal cramps, nausea an bloating with really swollen painful breasts after a light period that finished over a week ago now. my hormones must be soo messed up cause i never have sore b

Unlikely: Not sure that codon exists but if you mean oxycodone that is quite different than codeine.

Breast tenderness: These symptoms may be from some hormonal imbalance, the most common being pregnancy. The light period can be. Implantation. A urine pregnancy test would be helpful and follow up with your doctor is a good idea.

HPT: The light bleeding might not have been a normal period. I would encourage you to take a home pregnancy test. Be well.
