12 days late...

Heather

Hello everyone! So I’m 12 days late going on 13. I have took 2 tests and both were negative. One at 5 days past when my period was supposed to start then another at 10 days. Is there any possibility that I could be pregnant still? I am normally pretty regular if anything it comes early every month. Just looking for some feedback from others going thru this. We have been trying for you on 6 years now and it is hard!
