I need help...

Angel • 22 years young. A 3 year old and a 10 month old. Miscarried 2 babies. In a relationship with the most amazing man.
Ok I've never gotten pregnant after a miscarriage but me and my boyfriend are trying to get pregnant but not really trying at the same time meaning he pulls out. However Sept 29th I miscarried with our baby but this morning I noticed I'm spotting. Could it be that time of month or is it implantation? I don't really know what's going on...my stomach has butterfly feelings instead of the normal period pain...thanks!
