着床出血：这在孕早期是否常见？

着床出血在孕早期是否常见？

回答 Mary Marnach, M.D.

着床出血是指少量浅色点滴出血或流血。这通常发生在受孕后 10 至 14 天。着床出血很常见，通常并非问题的征兆。

当受精卵附着在子宫内膜上时，可能会引发着床出血。着床出血通常发生在预计的月经期前后。但着床出血量比月经要少。

有些人不会出现着床出血，有些人则可能没有注意到。有时，着床出血容易被误认为是血量较少的月经。如果发生这种情况，您可能不会意识到自己已怀孕，这可能会导致误判宝宝的预产期。胎儿超声通常在孕早期进行，可帮助准确判断宝宝的预产期。

着床出血量很少，会自行停止，不需要治疗。如果您发现自己在孕期有任何阴道出血，请联系您的医务人员。
