I have been having cramping on and off since the 26th in my lower back and lower belly. The 28th i had some pinkish brown spotting on my liner. It went away. The 30th i had some pinkish color when i wiped. And may 1st i had some pinkish brown on the toilet paper onky when wiping. I had a short period april 16th ended april 18th. Dtd the 21st 23rd and 24th and 28th. All preg tests negative. What was your appetite like in early pregnancy? ?? I eat but never feel full.
