Womens Conditions Forum - P.i.d. - Still Painful After a Week of Antibiotics

I'm 21 years old, generally in good health other than this problem! I'll explain as fully as possible, sorry if this is very long...

I went for an STI screen a couple of months ago, was all negative apart from B.V. which I was given Metronidazole (I think) for. At the same time I mentioned to the doctor that I had been having some lower abdominal pain; he gave me an internal examination and ruled out P.I.D. I was fine after that, but over the summer suffered from a recurring ear infection which I was on numerous courses of antibiotics for - Amoxicillin twice, and Cefaclor/Cefalon (can't remember the name). I then developed an infection in my wisdom teeth and was given Metronidazole again. I'm not sure if any of that is important but I wanted to point out the amount of antibiotics I have recently been on in case it has any relevance.

Moving on...

I took the morning-after pill about a month ago (I am on the pill but I had been on all these antibiotics and didn't want to take the risk). My period after that was 5 days late (started on the 3rd September), lasted for longer and was very heavy and more painful than usual, with terrible mood swings and lower back pain which I don't normally have. I put this down to the morning-after pill but about two days after my period had finished I began having spotting with thick, clear sticky discharge and blood clots, unlike my usual period blood, accompanied by a slight fever, occasional shooting pain in my legs, nausea and excruciating lower abdominal pain in a very specific area on the left. I went to a GUM clinic for testing and all the tests were negative but I was diagnosed with supposed P.I.D. due to the symptoms I was displaying (I'm at a loss as to how I got it; both my partner and I are STI-free - could it have been the B.V. from a couple of months back?). I am on a two-week course of Ofloxacin (400mg twice daily) and Metronidazole (400mg three times daily). After I had been taking the antibiotics for three days I was feeling worse, the pain had spread to the lower right of my abdomen aswell, my lower back was agony, I kept getting sweats, dizziness and headaches and on the second morning of taking the antibiotics I woke up genuinely feeling like I was going to die. I don't know if these were side-effects of the medication but I felt awful, so on the third day I went to A&E - still in terrible pain and still spotting - and was told by a doctor to basically deal with it, keep taking the antibiotics and take painkillers and anti-spasmodics for the cramps. Now I have been taking the antibiotics for 8 days and I feel generally better without the feeling of heaviness and weakness I had before, but yesterday the pain in the lower left of my abdomen has returned. It's certainly not as bad as it was last week but I am still worried. It's the same kind of cramping pain as before, and it's worse if I move around or do anything, so I've been pretty much resting at home. There's no bleeding, but I have started getting headaches again and I am not normally a headache sufferer. My period is not due for another week. The antibiotics have also given me awful thrush which is getting me down, and I keep reading on the internet about the high risk of infertility associated with P.I.D. which is worrying me.

Any advice would be appreciated, I will go and see my G.P. on Monday but to be honest I'm needing some reassurance right now! Call me paranoid...
