ovulation help... confused!

About two weeks ago I was getting faint lines on my ovulation test, this past week iv had nothing but today iv been getting very faint line again can anyone help?? I have a 36 adverage cycle so a long cycle, my husband has always told me we should have sex later on in my cycle but because glow always says I ovulate earlier I thought the third week didn't matter so much so we didn't really have sex slot. So confused can anyone help???
