Just told my husband I am pregnant.

So earlier I posted a picture of a pregnancy test with what looked like to me an indent. But women tweaked it and said that it had color so congrats, BFP. I'm 6 days late, 20 DPO. I told my husband that I was pregnant and now I feel like I made a mistake because I think I am but now that I've told him, I'm trying to convince myself I'm not? If that makes sense? I'm retesting in the morning with FMU but are these confusing feelings of regret common?
