Disappointed and Confused

So I been off birth control for three months now, my last period was about two weeks early, I have been known to ovulate two times a month in the past. Anyway on Monday I took a ovulation test and it was negative but close. Also took a pregnancy test and it was a strong positive, well took another one the next day and it was light but there. Last night I took one and there was NOTHING there but the control line. I’m due my period again around the 3rd. I’m just so confused on what’s going on. Am I pregnant or not. I got myself all excited and now I’m disappointed and confused. Any advice?
