Help me

So here's the deal. I have a good sex life with my boyfriend. We normally use the pull out on top of my birth control that I take everyday on time and have been on it for a year. About 2 to 3 weeks ago we had sex. We had decided that it should be ok for him to come in me since I have taken my pill well and have for year I've been on it. Well over this last week or so I have had a sore breasts and nipples, headaches and insomnia. All of which I had thought was do to something else like my pill or being sick. All day yesterday and the day before, i peed every hour on the hour without drinking anything all dayThe last two night I've waken up in the middle of the night a felt like I was going to vomit. What should I do? Should I test? What is the best test? I recently had gotten to the placebo pills and got no period but I don't usually get a period with my pill
