back on bc

Just curious, I was on birth control for roughly 9 months and came of to TTC but agreed wasn't a good idea for a baby to be brought in our life yet due to personal circumstances, went back on the pill end of July and now I'm noticing extremely sore boobs to the point hubby can't lay on them, weaker bladder and I want to say my nipples look darker at the bottom butt  it could just be me, although these sound like pregnancy symptoms is it just my body re adjusting? I stop taking pill in 11 days for week break not going to think anythin of it until I don't recieve a period just want to know if these are Side effects as I never had these before . Kind regards .
