Shocked by potential bfp, too good to be true?

I went off birth control in June after 12 years of consistent use; I’m almost 30. My cycle was a bit late last time around and now it’s coming up on 2 days late so I decided to take a test. The positive line did come up pretty quickly but my husband and I are still so paranoid and don’t want to get too excited! I don’t really have any other symptoms though beyond being bloated, minor breast tenderness and feeling tired. The only new thing is that I have been feeling a little whoozy at times? Anyone else experience this?
