I was on birth Control for a while and missed a week of it and had unprotected sex during that time. I did not take the pills for a while after that. I went to the health department where I live and took a pregnancy test it was positive but she said she was not for sure since the second line was not very dark but it was there. She told me to keep taking the pills.I have been taking them and I stopped. I started my period but it was not normal at all it was very light spotting and only for two days. I usually have my period for 7 days and it is really heavy. The doctor said that when you miss pills between that time you can be pregnant. I am gaining weight! I currently weigh 128 I usually weigh 119. My breasts have gotten bigger and they are very tender. I am also having back pain, and i am restless at night. Can I be pregnant? Can I still be pregnant if I had gotten back on the pill when they told me to and then stopped taking them? I am worried I want to know if there is a possibility.
