Hi I ended my period the 5th of October and I had unprotected sex. Just a couple of days ago my headaches returned, im nauseaus, I m more tired, I ve been eating alot more and craving food I don t eat,peeing frequently, and I haven t went number two like I normally doo and I ve been so irritable and emotional. Should I take a pregnancy test now or wait another week or wait until my period is suppose to start and see if I miss it?
