I had nice temperature rise on 5dpiui, i dont measure my temperature. But i can say my still feels hot.
Its so nice of you, i added you as friend,
It could be from either... I know i had implantation spotting with this baby at 7 dpiui, and didn't have a temp rise after implantation. But a lot of women have had that temp spike right after. I was also on progesterone suppositories right after my iui too. Did you have a temp rise? I looked at your profile but noticed you don't have an ovulation tracker on there.
