Positive or negative? Implantation bleeding or period?

I’m on 6th month of birth control and every week it’s sometime different. I’ve been much more emotional and tired recently, my boyfriend and I had protected sex 5 weeks and 4 weeks ago, I take my pill regularly and always use a condom too. As well I’ve been on the go for 2 weeks straight now with no stopping and haven’t slept well and gotten sick. My period wasn’t late and ever since I’ve been on birth control it went from heavy and long to short and light. Thoughtssss
