Minor cramps at night

joyce • I've been with the love of my life for 14 yrs. We're expecting baby #2 (boy) we are extremely happy and excited.
I am pregnant 6 weeks 3 days. During the day I do not feel it at all but once I lay down and my body is at rest I feel very little uncomfortable cramps like if I had my period. Is this feeling normal? I have a dr. Appointment tomorrow.
