I'm not sure what to title this

So my boyfriend and I had unprotected sex on my second fertile day and he came inside of me twice. As soon as I got my emergency contraceptive (EllaOne) I took it which would've been within 5 hours after. I didn't feel any symptoms that were listed on the box or any that weren't. It's like I never even took it. Lately I've been getting super sore breasts. I try to adjust them in my bra and it hurts when I do that. My nipples are super sore. I pee a little more than normal but that's too hard to keep track of. I've been nauseous but it also could be from this nasty Cali heat. I get headaches but also could be from he heat. My period is due in 5 days and I'm not sure what to think. Any opinions?
