Would you use grande lash serum during pregnancy?

I usually use a lash serum from rodan+fields that is pregnancy safe but ordered one from grande lash to try since my friend had much better results. Their website says not to use during pregnancy or nursing because they just haven’t done any testing for it, but do you think it’s okay to use? I’m 23 weeks and let my lash extensions fall out so I’m desperately needing to repair my lashes! Didn’t realize they had not done testing until I had already ordered/received the product. Has anyone else used this lash serum?
