So my fiancé and I have been trying really hard to conceive baby #2 I've been off of the nexplanon for about month but anytime he cums inside me I start to bleed like as if I'm on my period(even if I had already had my period the week before) any tips? Or advice you ladies could give. 
Thanks in advance.
