I'm crazy and already using opks. These are CD 3, 4 &5. When I had a short AF after my first mc I ovulated around CD 7 so just in case that happens again I want to catch it. I'm also charting my bbt and my temps have sort of leveled out. Should I stick to one opk a day for awhile longer or start doing two a day now? I'm so ready to ovulate!!
