okay i am ttc and my lmp was on feb. 16. i used an ovulation calendar and i had sex on the day that i supposedly ovulated. i really didnt think that the thing worked so i just went on with my life. but then 6 days later i went to the bathroom and noticed that i had 2 light pink dots of blood in my panties!!! my cycle was due 8 days after i noticed that. was that implantation bleeding and has anyone ever experienced this?? please help me to find out what it was 🙂
