Aw sis, I totally get the worry pero don't be too hard on yourself, maraming moms use efficascent oil during pregnancy without realizing, kasi it's been part of our routine na talaga! The thing is, topical oils applied to your skin in small amounts are usually okay, pero since you're worried and it's been frequent, best talaga to check with your OB just to be sure and get proper peace of mind, kasi bawat pregnancy is different at sila lang talaga ang makakabigay ng best answer for your situation. In the meantime, try other pregnancy-safe relaxation ways muna like warm baths or safe pregnancy stretches para sa anxiety mo, at go easy on yourself, the stress of worrying might be worse than the oil itself. Sending you calm vibes, mama!
