Yes. Both begin low, and increase. Estrogen increases much faster than progesterone. A day or 2 before ovulation, estrogen decreases sharply, while progesterone continues to increase. A couple of days after ovulation, estrogen begins to climb again, but the progesterone is way ahead of it (IOW, much higher). If an egg is not fertilized, then about 10 days after ovulation, both hormones begin to rapidly decline to minimal levels, which triggers menses.

The progesterone level peaks approximately 5 days before it crashes to reach the minimum (the minimum occurs on the last day of the cycle). And estrogen is back up to a moderate level at that point also. IOW, both hormones are up during the last week, but the progesterone level is much higher than the estrogen level, and it reaches a maximum level about 5 days prior to the last day of the cycle.
If this maximum point in the cycle is when the MC symptoms are triggered (early in the last week of the cycle), then either high progesterone is the problem, or the elevated amounts of the combination of both hormones is the problem. If the MC symptoms are triggered later during the last week (during the last 3 or 4 days of the cycle), then the rapid decline of one or both hormones is probably triggering the symptoms.
Does that help? Assuming that HRT maintains a constant, elevated level of both estrogen and progesterone (in order to prevent cycling by preventing both hormones from crashing to minimal levels), then it seems likely that the reaction would be triggered during the early part of the last week, in response to elevated levels of both hormones (or in response to a high progesterone level). If high estrogen were the problem, then the reaction should occur just ahead of the ovulation point in the cycle, because progesterone is still relatively low at that point in the cycle, but estrogen is at it's maximum level.
