Breast pain for 3 weeks 🤷🏼‍♀️

My boobs have been sore and enlarged, since a week before my last period(which is normal). The pains never lasted this long before though. I even bought new bras. I got a nearly positive opk about 9 days ago, which was pretty early. I’m now cd15, maybe 8 dpo!?!? and my boobs are still super sore. I’ve had a headache most of the day. Could it be a good sign that maybe my progesterone is elevated!? I’m confused. It is getting annoying though🤷🏼‍♀️
