I had my last AF on the 30th June finished on the 2nd July, first day was very light, second day was very heavy(never had such before) and the last day was very light also. On the 6th of July I had some bleeding again, very light started around 20:00 and the 7th was also very very light. Since then my nipples have been sore, they get worse day by day. I ovulated on the 14th of July. My nipples are still sore, feel a bit heavy than usual but the tissue have no pain, just the nipple. Could this be hormonal imbalance?
