Undecided Question

Abdominal pain and bloating for a week and a half – HELP PLEASE?

I've been having abdominal bloating and pain for a week and a half. At first it started out in the pelvic region but then moved to the lower abdomen. I am constantly bloated and achy, but it gets worse the longer I am awake (aka up and moving), and when I eat. Also, when I eat, I experience nausea. I went to the urgent care and they tested me for any type of bacteria found in my urine, and they also took an xray of my chest and abdomen. They found nothing. A couple of days later I went to an OBGYN who, once again, tested my urine, and also did a pelvic exam. She found nothing in the pelvic exam but said there was a TRACE of blood found in my urine that was typical of UTI's, but she said it could have been caused by a piece of skin falling into the urine sample. She went ahead and gave me antibiotics for a UTI, but it seemed she was doing this out of desperation because she did not know what was wrong with me. I have started taking the medicine but have seen no improvement. I'm hoping that someone will have an idea of what is wrong with me. I find myself in tears at night because it has gotten so bad. I'm not constipated or pregnant, and I have not changed my eating habits.
Some other facts:
I've had 2 hernia surgeries, one of each side of my pelvic. The right side scar has been hurting recently.
I've had an ovarian cyst but had no symptoms of it up until it burst.
I've experienced some other symptoms throughout this whole debacle such as lower back pain and pain on my lower right side.
I have not had a fever.
I have not had any of the typical UTI symptoms such as burning sensation while urinating and a frequent urge to urinate

PLEASE PLEASE HELP ME
