I think I may be pregnant but I m not sure. My husband and I have been ttc for 2+yrs. Several tests have all been negative so far; I am definitely late for my period though. I am either 5 days or 12 days, but am not sure on the exact date on my last pd. My symptoms include: mild to moderate cramping for the last week, noticeable moodiness and fatigue for at least two weeks, gas, extreme thirst. Last night after intercourse I noticed some light pink spotting, but it was very little and there was no more throughout the night or next morning. However, I just experienced another spot of blood, this time brickred and brown and thick. I hope I m not starting my period! I do feel some cramping, as I have for a week now. Please help!
