Could I be pregnant?

So I was pregnant in December and I had a miscarriage on the 24th of December. My husband and I have been trying for a baby for awhile now. I was on the pill for 5 years and have only been off of it for about 6 or 7 months now. My period was suppose to be today and I am a very regular, always on time and whenever I’m suppose to start it happens that morning that I wake up. No period today but negative pregnancy test. I’m just looking for some advice. Thank you in advance!
