I have used clear blue digital ovulation test strips with good luck. The first time using then I got prego, but last the baby at 10 weeks... Waited two cycles and started using it again with hopes of getting prego again. The last two days I had a faint second line which happened last time so me and my husband still did it just in case. This morning the second test line was supper dark but the weird thing is it popped up before the test line... Anyone ever had this happen... Below is a picture of it.
