Dear member, Thanks for writing to healthcare magic. Sometimes normal pregnancy is associated with a dull ache in lower abdomen. This is due to pelvic congestion. This may not mean miscarriage. As you have miscarried earlier you are anxious. I would recommend progesterone suppositories twice a day to prevent miscarriage. Also a early scan at 6 weeks will confirm whether you have a healthy pregnancy. If there is a fetal heart activity then chance of miscarriage is definitely less. Please write back with reports Thanks Dr Bhagyashree
