Hi AMA,
the straightforward answer is yes. HOWEVER, if you are perimenopausal you will have unexpected breakthrough bleeds, sometimes 2 or 3 times a month. The reason for sequential HRT is to control the bleeding to once a month. I was on continuous progesterone whilst peri menopausal to stop the migraines I had from progesterone withdrawal. The breakthrough bleeds were really annoying and sometimes so bad that I gave up altogether.
