I’ve been breastfeeding for one year but periods came back at 7 months pp. I’ve noticed a pattern that one week before my period starts I get awful insomnia. Lasy night I had four hours sleep and woke up at 430am unable to get back to sleep, I’m so shattered and emotional as I’ve got my baby to care for who is teething at the moment and constantly crying, feel like crying myself. Is there anything I can try or medication I can take ? I’ve never had this pms symptom before having my baby.
