Confused

I just got over my af two days ago and been kinda feeling weird lately. Yesterday morning I got off work and got into our house and let the dogs out and my heart started racing like it felt like it was going to come out of my chest, my husband and I decided to have sex as well and he said I was super warm almost like I do when I ovulate but I always ovulate late and I am no where near ovulation. Another thing I’ve noticed is that my boobs hurt around the outside and they never hurt after my AF only the first few days. Any help is appreciated or do I need to go see my doctor because I’m getting sick? Thanks
