...has been 16 days since I? Ok ...after trying for 8 years I had my first clomid treatment. Once I ovulated I was injected with the hCG hormone which is suppose to stay in your system for for 14 days .....its now day 16 and I took 3 pregnancy test which said yes..... I want to be happy but Im so afraid to believe and be disapointed that it was a false positive because of the injected hormone. Has anyone been given this injection before??? and if so did you have sore breast, headaches, and lack of energy with it? help!!!my provider will not be available till monday and not knowing is driving me crazy.
