oh hun! how scary.
Please do a test. It could all be in your head, but it's best to know.
Are you on contraception?
I must admit, the same thought has crossed my mind although we've either used condoms or I'm now on the pill, so it would be very unusual. I think it's cause I haven't lost all the baby weight yet and it's making me think my tummy looks like when I was early preg with Ash.
Let us know how you get on.
