Ay, i-understand ko ang worry mo kasi thyroid stuff during pregnancy is really important! Better to check with your OB-GYN about continuing levothyroxine kasi they need to monitor your TSH levels regularly, a few of us mums with thyroid conditions were told na the medication is actually safe during pregnancy, pero personalized ang approach depende sa dosage mo at kung gaano ka-stable ang levels mo. Your doctor might need to adjust the dose as you progress, so regular check-ups talaga ang key, and don't stop taking it on your own ha! Hope everything goes well with your pregnancy.
