My boyfriend and I have been having protected sex (using condoms and the pull out method, and checking it afterward every single time) for a while now. Over the past month after my last period (November 11), I started experiencing pregnancy symptoms- sore breasts, exhaustion, sensitive nipples. I assumed they were PMS symptoms & my period would be arriving soon, but now I'm approaching 3 weeks of sore breasts and my period is almost 2 weeks late. I took 2 pregnancy tests of different brands, and they both came up negative. Over the past 2 weeks, I started getting lower back pain right above my tail bone that radiates to my legs at times depending on how I'm sitting. Just a few days ago, I started cramping and thought maybe my period was finally coming, but it never did. I've been cramping on and off since then, and it gets worse with bowel movements.
The last time I had sex was 3-4 weeks prior to taking the first pregnancy test, so I'm assuming (HOPING) it's accurate.
I also had sex after I took the pregancy tests (all protected).
This has been really stressing me out, on top of the stress of final exams in college. The only thing I can think of is an ovarian cyst, but I don't feel any dull pain on one side or frequent urination.
Going to the doctor is an absolute last resort because I have no money.
Do you have any suggestions as to what might be happening?
