I get the scared feeling, I totally had a panic attack when the test came back with two lines (still on the toilet, hyperventilating - good thing hubby was at work!)... even though that was the goal! That was the cycle I had decided I really wasn't ready just yet for a child, and was going to resume taking the pill. I don't regret it though, DD continues to amaze me every day. Just breathe, and remember that not all symptoms mean the same thing. It could very well be from coming off the hormones in the pill.
Oh, and my cat considers himself my firstborn. He isn't exactly enthusiastic of DD, but he adjusted to her with no problems. I do my best to make sure we have our own special time at least once a day. Beautiful dogs!
