Just wanting an opinion on my chart this month, have only been doing it a few months but this months has gone strange, am hoping it's a good sign! All previous months my lp has been around 13 days, am on 7dpo today, yesterday my temp spiked higher than it's ever been before and today huge drop to below coverline. I've been getting cramps too, am swinging wildly between thinking it must be a good thing because period is not due yet and despair thinking it's coming early!
Could be an implantation dip, could be nothing. I've had temp dips in the middle of my LP before now and no baby. There are some stats somewhere on fertility friend showing that LP dips happen in both pregnant and non-pregnant cycles but are slightly more common in the former I think.
