Heavy and Sore boobs

Hey everyone. So I’ve had very heavy and sore boobs for about two weeks. AF is expected on Saturday and I haven’t had any pregnancy symptoms at all but my boobs hurting. One day I had nipple sensitivity but that was it. My boobs usually don’t hurt until a couple days before AF is about to show but like I’ve said they have been hurting for about two weeks. Has this happened to anyone and gotten BFP? I’m just so confused with my body right now. I’ve also text a few times and gotten BFN. Thanks.
