Im confused. Im on my cycle day 20, and I have slight cramps on my lower abdomen, its on and off, its been 3 days. I dont know if its ovulation or implantation cramps. My nipples also abit sensitive, and I have white and thick cervical discharge. Tomorrow Im going to have my progesterone check, because Im on clomid (100mg). Im hope its implantation. Please help me, do anyone ever go through this? If its preg symptom its it posible to show this early?
