Could I be pregnant?

I am curious, was this something your doctor prescribed or are you doing this on your own. I worry when I hear people talk about taking "natural fertility drugs" especially if they are wanting to conceive. Excessive amounts of natural fertility drugs can actually decrease fertility. Dependingg upon what you are taking, and how long you have been taking it, the hormone change could be why you are not having a cycle or why it is late. The hormonal changes could also result in tender breasts. Or it could be that you are pregnant, and if you are trying to say your tests were negative (like I am assuming) then OTC pregnancy tests can show negative depending on the amount of fertility drugs in your system. Strangely enough, you may need a less sensitive test. Your ob/gyn can do a serum hCG and/or vaginal exam to detemine it as well. Good luck, Susu
