my ovulation tests were blinking from the 12-15th. I supposedly ovulated on the 18th. No symptoms, temps, or anything. i have been taking the cheapies but decided to take these today. both were blinking but the cheapies said no. faulty tests, maybe? theyre both brand new. I thought cheapies detected it before these do. pregnancy also negative unless I'm not seeing anything that is there. here are the tests. please tell me what you think.
