Period after late term miscarriage?

Jamie • Gave birth to an angel 20/4/15 10:12am. 💕missing chloe💕Just waiting to feel whole again.
I lost my little girl at 23 weeks on the 17th of april. Her heart stopped and they induced my labour that Sunday and I had her on the 20th of April. I bled for around 14 days and was told we could start trying again when we felt ready and when the bleeding stopped. My husband and I started having unprotected sex again on the 5th of May, but I haven't had my period yet... Is there any possibility I could get pregnant right after 2nd trimester loss? I'm not sure when to expect it either... I would think sort of sting now? Any help?
