Hello. My period is due tomorrow and so I woke up today with what felt like menstrual cramps. They were painful enough for me to take Advil. I was so sure that I would see blood but instead there was only really light pink spotting that only appears when wiping. I also have clear CM. My temperature is extremely high at 99.4 and my boobs are really sore. I am 17 dpo and took Progesterone and Clomid this month. I'm pretty sure about ovulation due to CM and positive OPK. Any ideas? Does your period after Clomid go back to normal? Is it at all possible to have implantation this late?
