Hormones in a lesbian relationship

Hi all.

Me and my female partner have only been together about four months. What i want to know is how lesbians manage in a relationship together when they're feeling hormonal. I get grumpy and irritable when I have pmt and my partner suffers with PMDD so she's snappy and a bit spaced out during her ovulation period. As such we get emotional with each other a lot and are over sensitive to the others comments. It's driving me mad. I love her to pieces and she does me but it feels so hard in these periods. Anybody found a way to work around this?
