Confused! Help!

So, my boyfriend and I decided that I was going to stop taking my birth control after 6 years. He is against it and thinks it's terrible for my body. I'm not sure I agree, but nonetheless I stopped taking it. We both decided that we're ready for fate to decide when it's right for us to have a baby. ? I stopped taking it right before my last period; which was the beginning of this month. Since I stopped taking it I have had multiple headaches, moderate spotting a day or two at a time, pelvic pain, moderate to severe cramping, and mid afternoon puke sessions ? is my body just freaking out because I've been on bc for so long? Am I pregnant? Help please!!!
