I'm 16 1/2 weeks pregnant, and sometimes I have a small firm bump and then other times, like today, there is no sign what-so-ever, and I have some lower abdominal discomfort - it feels heavy and sometimes tender to touch. I have also been having diarrheoa in a morning, where as previously I was constipated.
There is no other signs I am pregnant - no breast tenderness since week 8 - only emotional and grumpy!!
I have looked on all the forums and things, and I know this is probably normal, and I did hear the heart beat last week at the midwife, but I can't help worrying because of these strange sensations and tenderness in my abdomen, and lack of anything showing.
Any advice???
