I am 41 years old and had a miscarriage in December 2009. LMP was 1/1/2010. Although I got pregnant after trying naturally (at first month!) my doctor put me on clomid (days 5-9) this time and Progesterone vaginal suppositories (starting 2 days post O). I O'd around day 18-20. On 12dpo blood HCG was negative. I am now on CD38 (18dpo) and have not tested since. I stopped Progesterone suppositories 5 days ago (cd32), still no af. I've always been regular. Anxious to get started on clomid again. Or, can I be pregnant? I have some minimal lower back pain and nausea but no tender breasts (just fuller). Please let me know what you think! Thanks.
