Hello. I started my last period 28/10. 35 day cycle usually however now 4 days late. Over the last few days l have taken several strip tests which have mostly been faint positives/some negative, 2 Clearblue rapid detection faint positives and a Tesco test which was negative. Experiencing cramping over the last 6 days and fatigue, no spotting. Just concerned if this is normal to have such faint tests as I’m very anxious, many thanks
