I had positive test since my Ovidrel that was 18 days ago. My last positive was yesterday which was 17 days from the Ovidrel. I started testing at 14 days past. Very faint but got really dark next few days Yesterday I had a positive digital (2 test sticks). I had one left from the pack and was so excited when I went to the bathroom I said wouldn't hurt. That was just now and it was negative! So I used the same urine with a cheap test and was negative to! How did this happen? I did have cramping these past few days and brown spotting but figured it was old blood. Could Ovidrel had stayed in my system that long? But my tests were getting darker not lighter! How is this! I'm going thru so many emotions right now. I'll be going for a blood test sometime this wk but not sure when I can just walk in. Help ladies! I'm all over the place! 😢😢😢
