Too Long Period and Need Remedy?

Ok--my most recent period started on 5/15, but it was very light spotting and didn't progress to a heavier flow. Usually, I expect my period to last between 4-5 days, but it didn't. At 7 days, I was expecting it to fade away, but it was still light spotting, varying from red to brown but with light cramping. I used only pantyliners and regular tampons. Two weeks past, and now I'm ready to call my OB because my flow is heavier/redder and I'm using maxi pads w/super tampons. I couldn't get an appointment until the following week, which would make this now three weeks. My stomach is so bloated it looks like I'm 5 months pregnant, my lower back aches, I also feel woozy and tired as well. My OB says that I probably didn't ovulate and wants to get me on the pill for a month to regulate my cycle. My hubby and I are not using contraceptives because we are TTC. Next week, I'm due for my June period, but am wary that it will either be stronger or the same....I'm tired! Anyone got any advice or feedback on what may be happening? Quick FYI--took a home pregnancy test a few days and it was negative. Though, one day I took two Alleve to get some pain relief and I felt like someone had kicked me in the head--I was so dizzy and woozy, and need to eat something immediately...UGGHH!
