Pregnant symptoms ?

Usually my boobs will hurt really really bad about 2 weeks before my period and this time they didn't start to hurt until 5 days before my period is due. They don't hurt as bad as they usually do though which is weird . And I've slept a lot these past two days and that's not normal for me eaither. I felt super sick last night and ended up having diariha.. Also have a head ache. I've also been very light headed / dizzy too . My period isn't due for 2 days. Too early to test ?
