OK so I am 4 DPO today....so why do I say it's the lonliest day of the cycle? Because there is nothing going on...That's Why!!! It's pergatory time!! it's not the worst day of the cycle...thats CD1 when AF shows up! But here's why it's the second worst day!! 4 DPO FF looks completely normal and no signs of anything...3 dpo is when you get your crosshairs so it's a fun day!!! It's confirmed ovualtion for you!! 1-2 DPO is when the temps start to rise confirming your others signs of ovulation!! 4 DPO All OV symptoms have now disappeared! 4 DPO It's too early for implantation signs 4 DPO Too early to Test! 4 DPO Your chart isn't interesting to other BnB chart stalkers!!! So 4 DPO is the lonliest day of the cycle for me!!!
