I'm 18 years old and I have had a miscarriage about 4 months ago then found out I had a cyst on my left ovary and that busted about a little more than a month ago, I haven't had a menstrual yet, I think I may have another cyst because I'm hurting some in my lower abdomen (like cramping), I'm gaining some weight, I'm having headaches all the time, I feel nauseated some here an there, I'm eating more than usual, and I have taken 3 pregnancy tests and all three said negative. Please help... Could I still be pregnant?

HP Tests can give false readings. Of course, if you've had sex (protected or unprotected) you could be pregnant.

You should contact your Physician - to diagnose you over the Internet, particularly in light of your recent miscarriage and cyst, could be dangerous.
