constant headache

so i posted about this a little over a week ago too. im 15 weeks 3 days and i’ve had a constant headache for probably almost 3 weeks now. i ended up being advised to go in & they said it could be a an early sign of preeclampsia but too early to diagnose. they gave me meds to try and they made me sleep for almost 18 hours straight and didn’t even get rid of my headache. i cant take meds like that because i have a two year old so sleeping all day unfortunately isn’t an option. i take 2 extra strength tylenol a day (1300 mg) and my headache will lighten up but never really go away. i drink water, i eat, im not overexerting myself, no injuries, nothing. i’m starting to get really irritated & feel super miserable because it never goes away and meds aren’t helping. any advice or has someone dealt w this?
