Aw mama, don't worry too much, a few of us have experienced that same thing during first tri, and our babies turned out perfectly fine, yung chest pain is usually just the pregnancy hormones and nausea playing tricks sa atin, hindi dahil sa amoy lang. Since you're at 13 weeks na, I'd still suggest bringing this up sa OB mo next visit para ma-ease yung mind mo, kasi they can check if anything else is going on and give you peace of mind. Try to avoid those areas sa work kung kaya mo, or step outside for fresh air kapag naamoy mo yun, yun ginagawa ng isang friend ko and it helped. Sending you good thoughts, mama, first tri is stressful enough na, pero you're doing great!
