feeling confused/frustrated

Kayla

okay so currently my period is 4days late and I'm still getting negative tests..I had implantation symptoms about 5-6days after ovulation and have all kinds of pregnancy symptoms.sore breasts,intense cravings,nausea,fatigue,and now a massive head cold.I'm not sure what to do at this point if I am or am not pregnant..I feel like I'm going to have to wait around and see if I miss another period..

any advice???
