Pregnant or not?

Lindsey

So, my body has been doing strange things ever since I have started trying to get pregnant last month. I started spotting 3 days before my period was supposed to start and on the 5th and 6th day, I had some heavier bleeding, just in the mornings and then it went back to spotting. I am still spotting today, 9 days later. Pregnancy tests have come back negative. My periods are always very regular and only last 5 days with spotting just on the first day. I’m so confused! Could my tests be coming back negative but I could still possibly be pregnant?
