I am a 22 yr old female. I had my period Jan.12 bled for a week due to trying out NuvaRing and took it out the first day. It is now Feb. 14th and no period but some bleeding. Yesterday i started to get a pinkish brownish only when i wiped. Wore a pantyliner and nothing. Same thing today except when i wipe and go pee there are blood clots no blood in pantyliner. Could i be pregnant?
