I'm sooo nervous what do you think?

I took a hpt last week and it was a bfn I was supposed to start today I know the day isn't over but it's usually like clockwork and I haven't started. I'm going to take a test in a little bit but what do you think my odds are?! Was last week too early to get a true positive. We bd on all the right days, my hubby and I have been ttc for 3 minths and I'm so nervous!
