Pregnancy headaches🤯

Did your headaches during early pregnancy feel any different from usual headaches? I don’t even know if I’m pregnant yet, too early to test, but I’ve had headaches everyday so far for the passed couple days, and they feel just like hangover headaches. And I don’t drink after fertile window ends so I know it’s not an actual hangover. Also been more nauseous lately. Thank you in advance for any input or advice!💕
