No Hope, still here trying

Is this it, am I ever gonna get pregnant again. I'm blessed with two beautiful lil ladies but would truly love myself a lil boy. Unfortunately I've had no luck in the last 7 years to become pregnant. But see I've been tested & doctors say I'm fine yet I can't & haven't been pregnant since I made the decision to terminate a previous pregnancy. That same pregnancy/termination caused me to have an infection as I was given a termination & told it was ok to have the iud inserted in me all at the same time. So in the back of my head, even though I have regular periods & all my blood work has come back fine. I just feel like it's the cause when sincethat ordeal I haven't managed to get pregnant.
