Pregnant or just hormone changes?

I'm 19 and have irregular periods on birth control. I have been on the pill for a year. Now my last period was shorter than usual and was a week late. I'm still having sore breasts and nipples along with headaches and bad nausea. I also am feeling sick to my stomach right now and have been having frequent urination as well as a heightened sense of Smell.

Can you rewrite thses sentences?

Existing railroad tracks within the port are in total disrepair and only a few of them are in operable condition. Should these internal railroad tracks be repaired, the facility will experience a heighten sense of efficiency by increasing cargo mobility through north and south of the port area.

Pain in lower right abdomen...again?

2 weeks ago, I started having horrifying pain in my lower abdomen, accompanied by heavy vaginal bleeding (after my period was a week late). I waited 3 days before going to the hospital, when the pain became too unbearable. They ran every test possible, blood, urine, internal and external ultrasounds, cat scan, internal exam, pap smear and colonoscopy (I have Crohns disease, and they wanted to look and be sure it wasn't that). He suspected appendicitis due to the location of the pain, but I had no sign of infection in my blood nor signs of problems with my appendix on the scans. The doctor was a bit baffled, as not only did nothing look wrong, but all my tests showed I was in fact in excellent health. He said it may have been something called a chemical pregnancy, where I miscarried before it even had a chance to attach itself, but that was his only possible reason for the pain and bleeding. It subsided by that Sunday, and I felt fine last week. This morning, the pain returned in the same area, just as intense as before, and came out of the blue again (no bleeding this time though). This time, however, if I lay flat on my back, you can feel a very swollen something (I'm guessing a lymph node?) on the lower right side near my hip. It is beyond painful to touch. My breasts have also become so sore it hurts when the rub against my bra or shirt. I'm am now 99.999999% sure this has to be something to do with hormones or my female parts. I have had ovarian cysts before that have ruptured and caused similar pain and funny female problems, but in the hospital, they saw no sign of them when the did the ultrasounds. Before I go back and look like a hypochondriac after being told I was in perfect health 2 weeks ago, what might be going on? Anyone have similar symptoms? I'm looking for things to suggest my doctor look for. I'm well in tune with my body, and there is something very wrong, even if it's hiding from the standard tests.

Is my nose piercing infected?

I got my nose pierced a little over a week ago.. I clean it regualrily with sea salt and water.. the last few times cleaning the inside though, has made it pop almost all the way out, i have an L shaped stud by the way so it shouldn't just pop out like that.. but when i pushed it back in it was oozing yellowish clear gooeyness that hardens around the inside stem of the stud, and around the jewel of the stud.. is that an infection? it doesn't hurt much when i fix it back to place, or when i clean it.. it stings a teeny bit when i clean it but thats it.

Is my ear piercing ok?

It's probably infected. Put alcohol on the earring and your earlobe everyday & try twisting it. Thats what your supposed to do when you first get it pierced. You also may be allergic to that certain type of earring. I have to wear 14k gold because of my ears. Just try not to wear fake things, like the cheap ones at Claires.
