Need some help please, my mandarin Goby is very pregnant. What should I do? Can you please share links of guides or any help will be much appreciated.

Thank you!
 
Incredibly unlikely. It probably has a blockage or tumour type growth.

They also lay eggs, and don't get pregnant.

Do you have photos?
 
Below is a 'pregnant' mandarin. They don't get pregnant they get gravid. This often only happens in the presence of a male and a good food supply. So do you have a male and female?
BTW you don't have to do anything. They will spawn eggs (at night) which float and become food for corals, amphipods and such.

If your mandarin is gravid and you want to try rearing the larvae:
Yes, people have had success with these (see the threads linked in the post of thread below - the post below also has some general aquaculture advice).

I've heard it takes ~13 hours after spawning for the eggs to hatch.

For food, you want Parvo pods (Parvocalanus crassirostris) - though I've heard that Ape pods [Apocyclops panamensis] work too - for the first foods (which they should start eating after ~48 hours). Then around day 7-14 (when the fish start to settle at the bottom of the tank), introduce Tisbe pods (Tisbe biminiensis). You can start training them onto prepared feeds (like tiny pellets) at the same time as you introduce the Tisbe. Around day 25 or so, they'll be able to start taking Baby Brine Shrimp (Artemia spp. - typically Artemia salina - nauplii), and they'll be ready to transfer from the rearing tank into a grow-out tank until they're large enough for a normal tank.
