HI.
Thanks for your query, read and understood the problems. 
The rules of the Surgical fields have to followed strictly to avoid such complications. 
Since you had an 
appendicular abscess you should have got operated after a few weeks from now on- but unfortunately for you there is a similar problem. 
Only 
CT scan of the abdomen can tell us whether there is a recurrence of 
Appendicitis or something else. 
It is OK, we have to face the problem. I would advise you the following:
Get admitted, get started on intravenous fluids and antibiotics and supportive medicines . 
Get he blood counts ans all necessary tests. 
CT scan to confirm. 
Surgeon would assess the possibility to operate or wait for 6 more weeks depending upon your response to conservative management. 
This does not look to be associated with female related . 
Do not worry , a proper diagnosis and treatment would help you out, 
Afterwards get operate at an appropriate time.
