So I got a call from my dr last Monday saying that my LH and my FSH were reversed. He said that my FSH was high and that my LH was low which meant that most likely I was anovulatory. He asked me about my periods and I told him that they had been regular except for this one. My cycle should have started, my cycle should've started between the second and the sixth but it hasn't yet. I told him I was late and he said the only other reason why my levels would be like that was because I was pregnant. I have tested every day since Monday and all my tests are negative. Do you think there's any chance that I could still be pregnant and not get a positive yet? The waiting, the not knowing is killing me. Getting pregnant has been the most important thing to me in my life for so long, I don't think I could handle it very well if I couldn't do it without fertility drugs.
