Hi ladies

I have noticed in the past year that I'M getting a sort of "pms" type roller-coaster very near ovulation. Since I've been tracking my cycles I've realised that I will systematically get very teary and emotional leading up to ovulation. Have any of you experienced this? Does anyone know which hormone may be causing this? I'm finding it particularly hard as this is the time we should be enjoying TTC and instead I'm feeling a little depressed and lonely each month 😢
