missed 3 pills

Se
I'm on the pill (Lutera) and I forgot to pack my pills with me this past weekend, so I missed 3 days in a row. My boyfriend and I had unprotected sex 3 times over the weekend and he finished in me every time. I read the directions on what to do if you miss a pill and it said that you can still conceive during the 7 days after you start the pill back up. I'm a week away from expecting my period and have mainly been tired (insomnia), have heartburn at night, peeing at all times of the night, constipated, hungry, bloated, and it hurts to even wear a bra. Has anyone gone through this before? Not sure if it's my period or what.
