月经来潮
menses
- 如果受孕发生在停药后的第一个排卵周期，那么可能不会发生月经来潮。
If this happens during your first cycle off the pill, you may not have a period at all. - 这些症状通常是可以预知的并有规律地出现于月经来潮的前两周。
Such symptoms are usually predictable and occur regularly during the two weeks prior to menses. - 如果在妊娠前至少出现一次正常月经来潮，那么某种程度上可以更容易判断排卵时间和胎儿足月的时间。
If you have at least one normal period before conceiving, it will be somewhat easier to estimate when you ovulated and when your baby is due.
