Hi my name is abby. I am 18 years old and think that i may be pregnant. I 1st thought that i was pregnant in march. I had my last normal period in mid febuary. I took 2 pregnancy test and both had come back positive. I then went and got a blood test and it came back negative. I had asked the dr. why i was still having symptoms and why i still had not had my period. and she responded with that i might have miscarried and that it was just my cycle getting back on track. She did have me come back for an ultrasound or anything. I didnt have a period until late april. and then another one in early may and then late may. i thought that i was pregnant and took two more pregnancy test. one was negative and one had one solid line and one faint line. so i just figured i wasnt pregnant. i had another period early june. and i still feel pregnant if that makes sense. i am still having symptoms although minor. they are still there. i have hypothyroidism, high blood pressure, and am about 25 pounds overweight. i have been exercising daily by running anywhere from 3-5 miles a day and have been losing weight but my mid section seems to be getting larger. i also just quit smoking about a week ago. is it possible that i could be pregnant and just having false negatives?
