Very very painful/sensitive breasts TTC

Hello,

I'm totally lost. My breast are so sore and feel like balloons and even look different. I've also been very neautious in the morning. I'm recovering from nasal surgery and I'm scared I might be pregnant only because of recovering medication I took. We had a lot of sex during the peak time. I shouldn't have my period until two days. Is it too early to test? When's a good time to test? Could sore breasts and morning neousia (can't spell) be a total coincidence??
