Yes. Four weeks from the first day of her last mestrual period is enough time actually and easier to calculate than conception.

Hmm… Usually you can get a pretty positive result after the first day of your missed period, however, it can vary woman to woman. I’ve heard of some woman not registering on a home pregnancy test until they were a couple months along. An ultrasound or blood work are other ways to see if you are. Just be patient, thats the key to being pregnant as hard as that may be.
Good luck!
