I am 29, and am TTC. With my first son, I got pregnant within 2 cycles of trying. He is now almost 3. The second time around, I got pregnant in the first cycle, but miscarried at 9 weeks. It was a partial molar pregnancy. That was in July. I started TTC again in January. My cycle lengths since then have been (in order) 35 days, 39 days, 42 days, and now I am at 46 days and counting. However, I have had light spotting on and off for the past 9 days. Base on secretions, I thought that I ovulated about 17 days ago, but now I'm not so sure. Took a pregnancy test 4 days ago, and it was negative - also don't feel pregnant at all. I know I've only been trying for 4 months, but should I see a fertility dr? It was so easy the first two times - I'm afraid something may be wrong now. Why am i spotting and why are my cycles getting longer and longer? Any advice would be appreciated. Thanks!
