Need advice from women who also had a miscarriage... help?

How quickly can you become pregnant again after a miscarriage? It’s been 2 months and 2 weeks since I miscarried. I’m still grieving, so I’m not trying by any means. But if it ‘happens it happens’, I’m actually being more careful then anything. My loss was at the end of February, and I just had my ‘first cycle’ April 14th. It was my first pregnancy, so my first loss as well and I’m very very depressed, so my stress levels are high. I’m looking for advice from women who have had miscarriages, because maybe they can help me? I think I may have ovulated this past weekend, and my fiancé and I didn’t use protection for the first time since this happened (I want to use protection because I’m scared to lose again and of course we aren’t ‘charting’ because we aren’t trying). I’ve been very moody the past couple of days, my stomach is very achy all of a sudden, I’ve been more hungry too (strange cravings of things I’d never eat). Do you think my mind is just playing tricks on me? I’d really like some advice, I feel like I’ve been bombarding my OBGYN with enough issues of concern, thanks so much. I know it’s possible to be ovulating, but I’m irregular to begin with. Help?
