Not sure if I'm prego....

So last week im pretty sure I got my period. Bleeding pretty heavily but for a short amount of time. Me and my boyfriend have unprotected sexual all the time. Lately I've been peeing like crazy, fatigued, cravings, headaches, but no morning sickness. With my last baby for the first four months I couldn't keep anything down. I'm just not sure. Wanting opinions before I get my pregnancy test in the morning!
