hould know this already being as I have been pregnant 2 x before.

Anyway my S.O and I have been trying for another baby. My Glow chart told me I will be ovulating from march 30th - April 5th well according to glow on april 2nd there was a 23% chance of pregnancy. The 3rd was 33% chance. Today is April 4th and I have been cramping and felt fatigued enough to take a 4 hr nap. I guess my question is: is it possible I am pregnant and maybe the symptoms are showing sooner because this would be my 3rd pregnancy?
