Is this even possible?

🌹K.

Is it possible to only ovulate only 3 days? This is the first time I tracked my ovulation with tests because I had a good period this month (the first time in 6 months). And me and my husband bought preeseed. I took a ovulation test Saturday and I could see the very faint line and it would get darker everyday besides today. It get fainter then the one yesterday. I thought maybe it was just the test but I took 4 more and they were all really faint. I’m not supposed to really get a positive till Wednesday. And me and my husband used preeseed last night. And when I wiped this morning it was a light brown ball of mucus that came out of me. Is everything okay? Like it said this is my first time doing this so I don’t know what to expect....I was really hoping for that big bold ovulation line Wednesday but I don’t think that’s going to happen...
