Deb with all my pregnancies i never felt pg and without a DR saying i was i wouldn't have known i was.

When i was pg with Kimberley i didn't find out till 13wks so it's can be done going through the first trimester without knowing and if i hadn't done a HPT then and had a scan a few weeks late who knows how long it would have been till i found out.

If you are worried about things see if you can have a BT done.
