Does the woman's previous waiting period (one and a half months) count for her if it was interrupted and then resumed, knowing that her husband's death occurred four months ago?

The 'iddah (waiting period) for a woman whose husband has died is four months and ten days, starting from the husband's death. There is no harm in the woman in 'iddah going out during the day to fulfill her needs and necessities, but she must not spend the night outside her home, nor should she go out at night except out of necessity.
