Hey guys, can anyone please be so kind to take the time to tell me if these pictures are of mold or not? And if so, how "Bad" is it? And if not, what is it?
They are on my bathroom ceiling.

Thank you very much in advance I really appreciate it.

Apologies for not replying sooner Michael. It's very difficult to tell anything for sure from your photos. However, it certainly looks like there is some mold or damp affecting your ceiling. To make sure I'd recommend an affordable, scientifically-proven mold test kit which you can buy online such as these Diagnostic Mold Test Kits from Micro Balance Health Products. They're easy to use if you follow the enclosed instructions. Alternatively, if you're living in rented accommodation then you should alert your landlord immediately (if you haven't already) as mold is a serious threat to health. To take it further you would be looking at having an environmental health inspector look at the issue and your property as a whole. Whatever your situation, please do make sure to at least test for mold yourself with a proven kit or get a professional in. Mold is not something you can ignore in any circumstance!
All the best.

I am not sure after seeing the picture. It is not possible for me to answer after looking at this picture. Try to contact the concerned person nearby you who can do a home visit at your place.
