Kinda funny story

So there's this girl I work with and the other night she said that there's a possibility that she's pregnant and she went a bought tests... She explained she took one and it's said "low" on it and if you are pregnant it's supposed to say "high" with a smiley face. I guess I didn't know you could be highly pregnant or low...she showed me the box after work and it's an ovulation test and she's been taking then every day for 4 days  😂😂 girls please tell me you know the difference between an ovulation and pregnancy tests!!
