Hey Juniper, no idea if this helps or not, buti used to find that if AF had stopped and I did accu within 2 days of it stopping - then it would start again and last another 2 - 3 days! Buti have 8- 10 day periods anyway and generally can't leave the house on day 1 or 2 as I am just bleeding too heavily

Prhaps the accu stimulates the uterus and that causes the bleeding to start again, if there is anything even slightly less? I also find my cycles go haywire after I've been on progesterone support. It would never have been possible for me to do back to back FET's or cycles if I had have needed to... I used progesterone pessaries with my natural bfp's butnprob only cause my OB was also my FS? Fingers crossed the bleeding stops asap!

Xx
