I had a miscarriage on oct 22, 2012 and have not gotten a period yet but I think I ovulated on nov 15, 2012 because I had some cramping and for about the next 8 or 10 days I had light cramping with no bleeding. I thought maybe I would get my period but nothing and now I have spider veins on my breasts with the sweat bumps around my nipples, indigestion, bloating, constipation, congestion with light blood when I blow my nose, cravings for sweets, headaches, lower back aches and a neg. pregnancy test how long should I wait before I do another one or could this be something else? Please help
