My Husband And I Have Been TTC For Over 2.5

My husband and I have been TTC for over 2.5 years, I ovulated on Thursday and Saturday we painted (stained) a dresser outside in the garage in a well ventilated area. Didn't notice a strong smell or get a headache, but after about 30 minutes I went inside and started panicking that it may cause harm to the baby if potentially I was pregnant. It was only 3 days post ovulation but I'm still scared. What are the chances that something could be wrong if I am potentially pregnant?
