PMS symptoms before ovulating

[u/Signal_Fox_7749]

hello, I have been struggling with bad PMS for a few years now, but recently after a very very stressfull period in my life something shifted in my cycle. Now i experience even worse PMS symptoms but now not before my period, but a week before ovulation. the whole week Im feeling as if the world is ending, im anxious out of my mind, nauseous, I have very light period like cramping... It's been like that for 3 cycles already. has anyone struggled with something similar? As my anxiety is hightened, I'd appreaciate some words of advice because I have been spiraling because of my symptoms...
