Cycle length is usually 30/31 so next due AF on 5th/6th March. I think I Ovulated around 22nd/23rd due to sudden increased libido and CM was clear, wet and slippery almost like oily. But last two days which would be approx 5dpo - I’ve had lower back ache and period type cramp/achy feeling but not due AF for another 8 days. I’ve also had white sticky discharge in my underwear but internally it seems to still be clear and oily. Anyone have any idea what this all means. New to TTC so never paid this much attention to all these things.
