Please help!!!

My hubby and I haven't been trying to get pregnant yet, in fact I have an appointment with my doc next Tuesday... I have been taking ovulation tests today and the last two days. Tuesday there was a line next to the test line, but not as bold. Same thing yesterday (Wednesday), and now today there is no line... does that mean I likely already ovulated? My cycle is messed up big time and if I already ovulated it would have been only a couple days after my period. I just started my birth control Wednesday... wondering what my odds are... and thoughts as to if I already ovulated. I am trying to chart everything if we would decide to start trying again. PLEASE HELP!!
