Have a bad day..

Since i start taking BC my day is always not a good day,I've been taking my BC for a week now and still my body have a bad response to it.I suppose to clean the floor today,it has plenty of mess from painting the walls yesterday,but I woke up with headache this morning,i feel cold even if it's very hot and my tongue is bitter.I really don't know what to do now but if tomorrow I will still feel the same then I will stop taking my BC and think for the next step.I can't stand feeling this everyday .I already take 4 tablets of pain reliever to take the headache away but it ain't working,just making things worst..I'm really hoping that by tomorrow everything will be perfect so I can continue doing my chores.
