so today you are on cycle 18. Are you testing today? As someone mentioned earlier, I think you should test 2 or 3 times. I was testing way too early into the day and was getting what I thought was positives but learned that we always have an amount of LH in our system. That's the hormone that increases around ovulation then drops back down. Anyways, I started testing mid morning around 10 am again around 2 pm and then again at 6-7 pm. It ended up being better for me. Perhaps you should test again and take a photo of your tests today and post for us. We can all help you figure out. It has also been my experience and many of these other ladies too that our O day got pushed up or back depending on the length of our cycles. If this is your 2nd cycle maybe you are gearing up for what will be your normal O day on clomid. I would just keep testing and like I said, post those pics and we will help. We all understand the frustrations. I do have a ???? for you though. Why are you on clomid? Do you not have regular cycles or something or were you not ovulating? Just trying to understand see if we can help you with what we all have gone through.
