SOMEONE PLEASE HELP/GIVE ME ADVICE

My period is more than 2 weeks late, 16days to be exact. But I've been wiping blood these whole two weeks. I don't think its implantation bleeding because mine has clots. I've taken 5 pregnancy tests and they've all said negative. I had protected sex, but then the condom broke, and once it broke we stopped. I'm really freaking out. Someone please tell me what's going on or at least try and help me out here.
