Weird pregnancy symptoms?

Bea

Soooo ,I have had heartburn for the last 3 days that I cannot seem to get rid of, and today I had a severe and sudden pain in both Brest, that could only best be described as being stuck by lightning, or them being used as punching bags. After a few, the pain lessened in intensity so I examined them and found both Brest are knotted up somewhat.. Are there possibly early weird pregnancy symptoms? I’ve had other pregnancy symptoms to but all could be reading into them too much. AF not due till Christmas. TIA baby dust to you all
