bleeding all the time!

Bec

im 9 weeks pp and stopped bleeding at 3 weeks.. and had sex with my partner that same week. started spotting which lead to the most horrifying period of my life which finished the first week of the new year (6weeks pp) but since then iv bleed again a few days later (lasted a week), and have just started bleeding AGAIN! not sure what the heck is going on... i also started on the mini pill at 3 weeks pp when bleeding had stopped. and fully weaned at 5 weeks pp.

any ideas anyone?
