Implantation bleeding looks like dark,old brown blood not bright red like a period. I had it with my first daughter. As for crazy ovulating or not at all might I suggest a Clear Plan easy fertility monitor? it is extremely accurate and we conceived the first month of using it. Also, if you don't ovulate could your dr put you on Clomid? I have to take Clomid to conceive and so far 50 mg has done the trick and we got pregnant the first month trying. The "spotting" you are having is a good sign...hope you are pregnant
