Thank you for your query at DoctorSpring.com
I understand your concern.
I will request you not to take any more pills, as it messes up the cycle completely.
Since he did not ejaculate inside you, there is no chance of pregnancy, no one has ever been reported to be pregnant from precum, there are lots of controversies.
Only one pill would have been enough, but you took 2, and this may be causing excessive cramping and the other side effects.
You will get better, do not worry about pregnancy.
Feel free to discuss further,
