Hello, my period is due in 4 days. Im to anxious to wait, Im having cramping in the lower abdomen , which is unusual. Whenever I m on my cycle, I NEVER cramp, but now I am. I ovualted on the 16th, which I did have sex that night. My boobs are heavier and my nipples are extremely sensitive. I m extremely tired and I ve been drinking water like I m a fish lately. I ve been trying to conceive for awhile, and I m wondering if im pysching myself out. Can you please help me
