J.G.
I would go get the test done & ask your doc to do an exam... one of my co-workers didn't test positive, but infact was & the doc found out through the exam.
To be honest... I'm due in July & started showing about a month ago. Most people can't tell since my clothes are big on me, but I can tell & so can hubby. My belly is also "hard" and I started feeling the movement the end of last month... hubby felt it last week.
When it comes to little ones - it's always better to play it safe!
Take care!!
