Ihave'nt had my period since October and I've taken a pregnancy test and it was positive then I took more that came up negative but I still have signs what should I do?

You NEED to go see a doctor! You might not be pregnant, but you could be pregnant. Hopefully not, but you could have a tubal pregnancy, which can be deadly if not detected early enough! Go see a doctor!

100% correct! Please, please go see a Physician. If it is a problem of money and/or being discrete, check with your state, county or local health clinic or search "free health care" for your area. GO TO A DOCTOR IMMEDIATELY!
