Trying to conceive:9dpo, accidentally inhaled dimethylformamide at work. is embryotoxic. have had migraine and tummyupset for one day. should i worry?

No: It would be very unlikely that this minimal exposure would create any problems.

Well, A one time is: Not going to cause a birth defect! not sure how it's related to the migraine or if it is. Early exposure to toxins result in miscarriage, not birth defects but it's not confirmed u are pregnant and low probability that this one time exposure would cause a miscarriage. Good luck but you may need to discuss the effects with poisen control. Gdluc.

No: Briefly inhaling a substance prior to the time that you can even detect whether or not you are pregnant is extremely unlikely to cause harm.
