How many eggs were in previous clutches.
Phos free calcium should be dusted lightly on the insects at each feeding but 4 a month and she should be fed every second or third day at this age and only about 4 crickets per feeding. I would use other insects in her diet too.
Calcium /D3 should be used twice a month on two of the days, two weeks apart lightly. Same for the vitamins. Be careful with D3 and orEformed vitamin A because they can build up in the system?
Now...the real issues at the moment are her dropping eggs, not burying them and with whatever is sticking out her bottom ...so can you post another photo where I can see what is sticking out please.
If it's (her) tissue it needs to be kept moist with K-Y jelly until it can be dealt with...and dealing with it needs to happen quickly.
