23 years old, 185lbs, 5 2 I am on ortho evra and dont usually mess up on my patches. A few weeks ago, I forgot to change my patch and I do a 12 week cycle, this happened on the 10th week. I figured it would be ok and so I just got my period early(LMP 7/24/14). The next patch day I forgot to put one on again until the next night. I didnt think anything of it and didn t use a backup method the following week. Since then I have put the patch on correctly but this past week I have been having nausea/vomiting, mood swings, strong sense of smell, migraines, and frequent urination. My period is also late 2 or 3 days and the only cramping I m getting is very faint on one side when usually mine are rough from the beginning. It took me a second to remember after all this that I had messed up my patch. I just noticed a few minutes ago that I m having some light spotting and more discharge. Could I be pregnant? I tried a home test, but after it coming up negative I realized the test is expired about a year, so I dont think I can trust it. I have no idea what to think.
