Someone please comment if u understand

Idk what’s wrong with me. I had a heavy period when I normally get it. But at least two or three days later my breast immediately started getting sore. And that never happened to me before. I did have sex twice last Monday which was protected with a. Condom and he did NOT cum in me either time. But I just don’t kno why I get these syndrome so early. I usually get PMS after ovulation phase . And I had the discharge I get around my fertile phase but i didn’t get it on my expected ovulation day. Could it have started earlier then usual .
