AF is now 5 days late...

Hello, ladies! I haven't been on Glow in a while. I guess you can say I gave up on ttc & just decided to go with the flow. Anyways, af was due on 12/1 & it is now 12/6 & im still looking for her with a flashlight, LOL. I have been having some pms symptoms, but not as hard on as I usually get them. I get cramps every now and again but nothing major. Definitely not like my usual AF/PMS cramps. I chalked it up to my period coming but now I'm not too certain. And I usually want sweets around this time and all I been wanting is Taco Bell lol I did take a pregnancy test yesterday but it came out negative so right now I'm kinda at a lost. I'm hoping that the test was just old or had a defect because I ordered them on amazon.com (it's the cheap dip sticks) I will be taking another one by Friday for confirmation but I also wanted to get you guys opinion. Can y'all tell me what y'all think is up? I know none of us are doctors but it's still nice to get other inputs
