Help!!!

K

So I took a day after on the 31 of July and had sex on July 30. I took this pill because the condom came off but was still hanging out but cum or lube was all over me and him. My breast have been hurting and tender for the last few days! I also had sex on the 2 of July and 11 of June. Does anybody know what this is? Has this ever happened to you? Any advice? Literally anything? Btw I always use condoms!
