can anybody calm me down?

ash

So i am currently at 12 weeks..and i had my tsh level at 4.3 at 6 weeks and i ignored taking medicines. Out of sudden i today googled the consequences of high thyroid level and i am devastated and cursing myself for not taking medicines. Can i start my medicines now or it has caused any damage to my baby??? I am literally in tears right now. Please if somebody had any experience related to high thyroid to share i would love to read..please thanks
