So I bled 6th-16th feb but my opks showed darkish I think I missed the ovulation day on my opks anyway since I got home this week Ile been feeling sickly and warm very tired and lots of watery discharge could I have gotten pregnant on that bleed as my discharge was rather sticky then aswell and my periods are all over and now my opks are very light xxx
