My husband and I found out we were pregnant back in early March, unfortunately after 6 weeks we had a miscarriage, before the miscarriage my cycles have always been 28 days. Never late, never early. Since the miscarriage I have had short 24 day cycles. Until this month I am now on cycle day 30 and no period, no positive pregnancy test. Has this happened to anyone else? I am not sure whether to worry since I have always been regular! Thanks everyone
