Confused....

From what I read and was told I had a chemical pregnancy this month. All positives up until like the day after af was due then all negatives. I've become a poas addict. Now af was due 11 days ago. No bleeding, spotting, nothing. Just light cramps and sore breasts here and there then nothing. Has this ever happened to anyone else? Could I possibly still be pregnant and just ending up having a late miscarriage? I'm so frustrated and confused because I was so happy after ttc for almost a year as of next month. I had to change my Dr appointment because the ultrasound tech wasn't there so I still don't know what's going on medically. Won't find out until later this week. Has anyone ever had all negatives tests and still had a healthy pregnancy and baby? Ugh, sorry for the rant. My mind is all over the place!
