Bleeding nipples, early pregnancy

Sara

Hey a few days ago I posted photos of pregnancy tests I’ve taken. First response and clear blue. Both have a very faint positive. Tonight when I got out of the shower both of my nipples were bleeding. I am in denial if I’m even pregnant because I had my period and right after my period ended I took a test just because I was feeling off. I’ve taken those .88 cent tests and test strips from amazon and digitals and all say negative, except the clear blue and first response. Both photos were taken within time frame. I have had back pain, increased gas and bloating, heartburn, and cramping. Now this.... this concerns me. Is this a sign of early pregnancy. If I am pregnant this will be the first time. I had a positive test in March 2017 but literally same day I took the test I miscarried and it was confirmed at hospital. Any advice would be great.
