10w 4days with EXTREME one sided headaches

Like the title says, I’m 10 weeks and 4 days and my next doctors appointment is soon but I’m semi worried I should go to the doctor sooner than later.

I’ve had extreme headaches with nausea up and down and what I can only explain as heat flashes. Has anyone experienced this? Am I freaking out over nothing? I googled it to make make myself feel better and online it says it can be a sign of preeclampsia or poor implantation.

Has anyone experienced this and still had a full and healthy pregnancy? I have PCOS and I’ve tried for 2 years for this baby so I’m really worried…
