However, if the fetal pole in one sac is not seen even at 6 weeks and 8 weeks of dated pregnancy, it may indicate an anembryonic (blighted) sac. The other sac with normal fetal pole and heartbeat may continue till full term in that scenario. 2) Fishy odor may be a sign of bacterial vaginosis.

BV needs treatment, especially in pregnancy, as it can trigger a preterm labor, or rarely an abortion.
