Okay, so I had a D&C on July 7 for a missed miscarriage. After that I only bled for a couple days and then I had my first normal period August 11 (right on time). We decided we want to try again, with the approval of my doctor. According to my normal cycle my period was supposed to start Sept 8. I took a test in the morning this past Sunday and nothing. Could my cycle be messed up even though I had a normal period last month? Or could my levels still be too low? With the last one my period had been 10 days late before I got a positive test.
