Kinda feel pregnany, kinda don't...help😭

So we had unprotected sex on my first day of ovulation, and im supposed to get my period in 4 days. My breasts have been tender which is not one of my period symptoms, it's usually when my legs feel restless. I keep having this feeling like my cycle is about to come on and I had some cramping about a week ago, also had lower back pain and have been peeing alot it seems like. maybe a headache in between. But im not really sure I mean with my 1st 2 pregnancies(both ending up in miscarriage) I didn't FEEL pregnant either....im hesitant to take a test because I haven't had a chance to miss my period ! should I take one now or wait ?? my cousin says now...
