Hi all, I am 28, my husband is 32 and we have been trying to conceive for 15 months. I have been told I have 'unexplained infertility' as all my structural tests are normal. My husband has a normal sperm count and I appear to be ovulating. I chart my cycles and one thing I notice is that my BBT doesn't rise very quickly or very high post ovulation although it DOES show a rise and I get a +ve OPK. I also chart my mucus and all the signs suggest I ovulate. My progesterone level came back at around 20 ( on day 21) which my doctor said was 'equivocal' although, once I was referred, my fertility doctor at the hospital was unconcerned by this! I am considering natural herbs and acupuncture. I am not back at the hospital until May. Can anyone offer re-assurance or advice on my situation? Any comments and thoughts are greatly appreciated.
