Tender breast & nipples, sore ribcage edge and lower abdomen, taste of blood in mouth, headache, frequent unrine, bloated w/ gas. could i be pregnant?

Possibly: Pregnancy can cause all kinds of symptoms. There are other problems that can cause the same symptoms. The simplest way to find out is to take a pregnancy test. If you have missed your period, it is possible that you can be pregnant. I recommend you follow up with your doctor as soon as you can to address your concerns and symptoms.
