PRE SEED!!

So I started using pre seed the first of this month. Later that night I started my period which it lasted for 4days. Used pre seed again once I got off. A day later started heavy bleed for like a hour or so. Skipped 2 days without using pre seed. Then begin experiencing pinkish brownish bleeding. Now still using pre seed. Experiencing mild cramping,nausea, tender breast,fatigue, mood swings. And to top it all of af supposed to show again at the end of the month on the 28th. Has anyone experience this using pre seed first cycle. What are my chances of getting my bfp.
