I have the clear blue smiley ovulation sticks that tell you high and peak fertility. I am on cd8 today and my period app says I will have a 30 day cycle this month based on 4 ish years of inputting period dates. When should I start using the sticks? I have 20 so don't need to skimp but would tomorrow morning be too early? As per my app I am due to ovulate on Saturday 15th and fertile all week leading up to it but I have been reading that women can ovulate much earlier or later than the average 14 days after period start date. I was thinking regardless of the ovulation stick result that we should dtd every 2 days till after I supposidly ovulate
