need advice, really down!!

[30thMarch2010]

I had a d & c end of Aug folowing a mmc at 9 weeks discovered at 12 week scan 2 days before d& c. I bled for 2 weeks then got af on 27th Sept which seemed normal. I had completely stopped bleeding after 6 days but a few days after started spotting ( tiny bits of blood in discharge) no need for pad. Only occasionally happened. Now its 9 Nov and I still havnt had next af, normal cycle 30-33 days. Stopped spotting completely about a week and a half ago. Took 3 test all spaced out from cd 30 till today. I don't know what's happening...I don't know whether spotting delayed cycle? Or I was worried I could have low progesterone? Or anyone got any other suggestions????? I have no sign of being preg or af coming, its getting me down since I tried for a while ringer preg with miscarriage and it feels like its taking forever again, I'm so worried its something wrong with me that's stopping me conceiving/ causing miscarriage? Any advice would help!!
