I could've sworn posted this earlier. I don't see it though ๐Ÿ˜•.ย 
I had a chemical and got a positive ovulation test the day after AF ended. I tested the day after I got the positive, and it was negative. All of these test were within 3 mins. I tested again today and it's getting darker again. It's possible to ovulate again after one, correct?
