So I've been taking the clear blue advanced digital test and I took it Tuesday around 5:30 I think and I got a blinking smiley but then around 8:30 I was getting really crampy I didn't take another test. I took one Wednesday morning and it was a solid smiley. So me and my husband BD'd Wednesday night around 8 because he had to work. My question is... should I have tested Tuesday night? And could I have missed the egg by waiting? We plan to do it again tonight just to be safe. We couldn't do it Tuesday because we were away with my sister and my nieces and they were in the room next door and my husband didn't feel comfortable doing it with them next to us in the next room.
