Crazy to think how this pregnancy started. I had my IUD removed, had sex with my husband once and got pregnant. But we had no clue for 9 weeks. several negative tests. wasn't until I went to the hospital for something unrelated and they told us. Then my doctor was concerned about my short cervix and prepared us for a possible miscarriage or cerclage. By 17 weeks my cervix more than doubled in size. And here I am, 37 weeks, on maternity leave, just waiting for our baby boy to arrive.
