Cervix pain - no diagnosis from doctors

i am 25 years old, partner of 3 years, and went to the doctor last Thursday about painful sex and discomfort in my lower abdomin, swollen stomach and pressure, discomfort walking, reduced appetite, frequent bladder and no period for 7 weeks, 

i was examined by the doctor and sent to A&E with a referral letter.

swobs were taken, tests for STD's, infections and bloods for kidneys, urine, pregnancy, and inflammation all came back clear or negative.

i was sent to see a gynaecologist that day and my ovaries, Fallopian tubes and womb are fine, towards the end of the internal examination the doctor said I have an erosion of the cervix, to make an appointment with my GP to get a smear test, 

after all that my period arrived the next day, (Friday) so this put off the smear until today (Wednesday), I'll get back to this bit*

 

however on Monday morning I started to get a strange sensation in my lower abdomen and legs, my legs ached and the pain moved into my lower back, I rang the doctor again and they asked to see me again, a different doctor available, she examined my stomach and sent me back to A&E with the intent of me seeing female surgical, she advised it was not a problem with my reproductive system and that it could be my bowel?????????

again all the tests came back clear and nothing showed up on an X-ray! 

Back to the smear*

Once getting the smear teat, I screamed in pain and pointed out to the nurse that this is the pain I sm getting, I can hardly walk and only have been given cocodamol 30/500, I cannot take another week off work,

 

has anyone else had a similar experience and what was the  outcome?

how long does smear results take to come back? 

I feel like I am going mad as all the doctors are telling me I'm fine! I'm not fine and as any woman would feel, I'm worried about long term damage, when I was 19 i had the same issue and was told It was PID and it took 8 weeks to heal and for me to get my life back, I dont have that luxury to be off work, 

a doctor in A& E mentioned endometriosis?
