Thanks so much ladies. Just got home from appointment. Progesterone test showed that my levels are quite normal but the GP was still concerned about my short luteal phase. Unfortunately DH's sperm count was low so she's given us a referral to go see a FS. She said to just go chat with him, see what his plan would be, the costs involved etc and then we can make a decision whether to start with him right away or give it more time. DH and I have agreed we'll go chat with him asap and see what lies ahead before making any decisions...
