Am I psyching myself out??

Ok so thus month the has been very weird for me. Me and hubby have been BD every other day or every day, and during my glow fertile window it felt like he ejaculated in my uterus and that's the first time I ever experienced that. And I've been waking up a feeling nauseous I'm tired constantly, very forgetful too. Right now I've been having cramping and lower back pain, and my breast have a tingly stabing pain in them... my af is due 7/15. Could these be symptoms of pregnancy? Been ttc for over a year and this would be our rainbow baby if I am. Oh and do you think I should test asap or wait till friday??? I really want to know but don't want to get my hopes up. Oceans of baby dust to all!!!
