Help.... not sure what to do....

This is my second month of trying for our rainbow baby, we've been doing it several times a day..... my period is due in two days n usually I can sense that it's coming and I'm currently not..... my body feels "weird"/different.... my breasts hurt, having trouble keeping certain foods down & extreme nausea & being exhausted.... is this a sign I'm pregnant? How long should I wait after my period date before I take a test?? Don't want to do it too early to get my hopes up.... can anyone help me with some advice?? Don't really have anyone to talk too....
