Hi. I’m new to this strips I used to Clearblue OPK but it’s getting to expensive after long time TTC
i started using them on day 4 just not to miss my surge but they getting lighter? Normally I ovulate day 12 based in my Clearblue OPK. Also Clearblue OPK after peak you have around 24/36 hours before ovulation. Is it same with LH strips?
