Fro m what I understand is that after you get a positive ovulation reading, you need to have sex for three days straight. I just been doing it everyother day. I don't want to miss out. Do you mind if I ask how old you are? Just to see your vitality in fertility.
How long does the ovulation period last?
I have been using ovulation strips. I've read that some women have had ovulation during af. I just use them because I'm older now andmy periods have been four days long. When I was younger, it was 14-16 days counting from your first start date of af. I hope this helps.
