Pregnant?

Meghan
My boyfriend and I had completely unprotected sex (we usually just use withdrawal) but twice we didn't and I haven't gotten my period in 2-3 weeks. I'm emotional, bloated, nauseous and just overly sensitive inside and out. I've been breaking out on my chin which hasn't happened in years. I'm fatigued. But I took a pregnancy test two days after my missed period and it was negative. I want to take another but honestly, I'm scared. I also think I'm wishfully thinking about wanting to be pregnant but these feelings are real so maybe it's just me being weird. I feel like I would know if I was pregnant, like I could feel it.
