Bad mood periods

For context I’ve got a 19 month old and we stopped breastfeeding around Christmas/ New Year time… Ever since then I’ve had absolutely awful moods during my period, especially first day. I feel low, angry for no reason and so irrationally irritated over everything. It’s so much worse than normal PMT. I’ve screamed and cried. I feel terrible for my partner because I’m a witch. My patience with little one is so thin which is so unlike me. Pain is next level too! Has anyone experienced this and how do you help it? I spoke to the doctors who just wanted to give me anti depressants but I’d much rather know the issue and deal with it as a whole and more holistically rather than just taking meds straight off the bat. Anyone? 😫
