Don’t want to be pregnant

Why did I get sore breasts right after my period. Before ovulation. IKNOW hormones can act different every month but this never happened to me before. I did have sex twice last week Monday but it was protected and he did not cum inside me and neither of the condoms broke. And IKNOW it would be to early to tell now. I also feel like my ovulation started a little earlier then normal, since I didn’t have the discharge i usually get on the day ovulation. My expected period is suppose to start in 7 days. The symptoms I have right now are VERY sore breast, bloating, headaches, emotional, back/side/hip pain, white discharge/tissue like discharge. Idk what’s up with my body this month but ever since my period ended I’ve had the sore breast immediately right after and idk if anybody has ever had it but i haven’t. Could somebody please comment if you think I should be fine . I don’t want to be pregnant 😞
