10 days late bfn

On August 23rd I suffered from a chemical pregnancy. This was my first time experiencing one. I bled from August 23rd - August 27th. Two weeks later on September 8th I got a solid smiley face on my clear blue ovulate test. I had sex ever day from August 29th - September 10th. After that I had sex every other day to every 3 days. My period was supposed to start on September 22nd. It never came, I have taken several test that all have come back negative. Today is day 10 of my period being late. I have 3 other children (ages 5,3,&1) and I’ve never had a problem conceiving or getting positive tests. So I’m confused and a little worried. Has to this ever halted to any of you ladies before ? Should I go to my ob now or wait a little longer ? I’m not experiencing any pregnancy symptoms at all besides fatigue. With all my of my other pregnancies my boobs were so sore and swollen by now. Could it be a problem from my chemical?
