Spotting while ovulating

Maegan • I am a stay at home mother. I have a wonderful three year old and fiance. He has four children from previous marriage and we want two more.
I spotted for about a week almost. I thought it was a period but I did an ovulation test and I had high LH Surge. I was so happy . I am having a hard time tracking my cycle. I haven't always had regular periods . Strange enough the IUD gave me a regular period some reason. I used it 3 years. I'm trying for my second miracle. I will just try to be patient.
