Non-Hormonal Birth Control

CarolAnne • A wife ,and a mom of 2 girls. Love my beautiful life

I've been on this birth control method (paragaurd) for 3 months , after having my daughter 8/22/17. so I had normal periods until now. I'm spotting way to early . If my spouse finishes in me, could the birth control force my period to start early , in order to avoid the pregnancy. I've had the skyla IUD before and it never did this.
