Question...am I crazy?

Hello everyone! I wanted to ask a question...my husband had a rough night last night, he came home and was feeling bad. He nuzzled in my arms for comfort and then we made love. It was absolutely amazing! Afterwards, we were enjoying the afterglow and I just felt...like I'd concieved our love child. Have any of you felt this way? Is it possible as a woman to FEEL when you've concieved? I know the only way to know for sure is to wait...and take the appropriate tests at the appropriate time....but I can't shake this feeling, what do y'all think?
