I miscarried in Feb 09 TTC this month

Hi, me and my husband found out we were pregnant back in January and were getting married in April! We are both in our mid 20's with no history of health problems. At 11 weeks I started bleeding lightly but my midwife said that can be normal which it is. However I didnt feel right and then after another week i was rushed to A&E with heavy bleeding and subsequently miscarried our first baby a day before our first scan so we never actually got to see him/her. The most devastating experience of my life, I felt so depressed and couldnt stop crying for weeks. Why is it when something like this happens you suddenly notice pregnant ladies everywhere!! Im really worried that its going to happen again, my husband says to stay positive but i find it so hard i keep thinking theres something wrong with me that caused it. My midwife recommended waiting 2 months before trying again and as my periods are back to normal we started trying again this month. Next week we'l find out if we've concieved. My family have been so supportive but because my best friend fell pregnant a month after me it has been tough talking to her as I didnt want her to be worried about her baby and I also felt quite jealous for a while and couldnt stop crying when she mentioned her scans etc. After four months now we are back on track but it has been really hard on all my relationships especially with my husband as I have not been myself since. You dont realise how much it can affect your life emotionally and physically. It has really helped talking about this on here. Thanks.
