HDB paint fumes... concerned

Dear mummies... I'm 6 mths pregnant and recently my HDB block undergone painting works. Particularly at the lobby the smell was strong on one of the days so I quickly tried to "escape" to another area while waiting for the lift. The smell was lighter (in wafts). As the painters push the paint ard sometimes I'll get wafts of it while I'm heading downstairs. Wondering if there's any cause of concern as I understand paint fumes are harmful for baby... very concerned. Pls advise..
