I have had 2 C-sections and one miscarriage (at 4 weeks) within the last 8 years. The miscarriage was 4 years ago. Now, have taken three home pregnancy tests and they are all positive. Noticed some light brown discharge/ bleeding after urinating. Has been going on for about 4 days. Today, after urinating, brighter red blood . No blood on underwear, just after urinating. What do you think?
