Help me?!
AF ended on the 20th of this month. Per Glow I start my ovulation period today however, just a moment ago when I went to the bathroom I had a think brown discharge/ spot when I whipped, I whipped again and nothing. My husband and I have done the BD everyday since my
Last period. But I'm sure it's to soon for implantation. Should I be concerned? Sorry for the TMI, thank you in advance.
