Please help

Is it normal to feel nauseas before period? Period is suppose to start in 5 day. I have had sex 3 times this month. They were all protected and he did not cum inside me none of the times and he pulled out before any of the ejaculations to make sure there were no leaks I put water in them and they were all good. My symptoms I have are very sore breast, sick to stomach sometimes; headache, acne, very bloated, emotional. Etc. should I be fine ??
