Ovulation

Hi I'm Madison , I'm New Here My Fiance And I Have TTC For 2Yrs Now , I've Been Pregnant Before But Had A Miscarriage At 6Wks . Glow Said That I Would Be Ovulating 05/03/15 But I'm Thinking It Happened In The Days Before Between 04/30-05/02 Because That's When It Was Egg White And Really Stretchy And Medium . I Didnt Check My BBT Or CP But I Remember Having Sex With My Fiance Three Nights During What I Thought Was My Fertile Days .. I Also Had Sex Yesterday Because That's The Day I Was Suppose To Be Ovulating And Today I'm Experiencing Sore Breasts And A Slight Twinge Of Nausea.. If Anyone Has Any Feedback It'll Be Greatly Appreciated
