When to use guided meditation for emotional openness per astrology?

Sometimes I find that particular moments of the month or periods in my life make me more emotionally sensitive — it is difficult to remain calm or be completely open-hearted. At other times, however, I feel calmer and ready to heal. It made me wonder whether the stars are involved with that beat. Could astrology guide me to use a time of guided meditation for healing that could help me feel calmer, lighter, and more emotionally open?
