BD today??

so we have been trying for a year. but really doing everything for 4 months( opks, eating good, vitamins, BD on certain days) . last month I never got a positive or I missed it. end of last month I got period 1.5 weeks early. Thought it was implantin till it got heavy) Doc said treat it as AF unless it starts again. I was freaking being I've lost 4 babies. And I was starting to worry I don't ovulate anymore after surgery from ectopic pregnancy. I only have one ovary and tube now. But this gives me little bit more hope. yesterday was little lighter (it's at home I'm at work so I can't post pic for comparison). is this my positive and go on the BD for next few days? I don't wanna get too excited to jump on hubby when I get home yet.
