Hey everyone! I am now 13dpo and period expected in 3 days. Over the last few days I’ve had a dull ache in my right lower abdomen, yesterday (12dpo) myself & hubby had sex before he went away for work, this resulted in some brownish discharge. It’s possible that it may be some blood before my period but I’m stressing now on whether we might have impacted implantation. Does anyone know whether sex could potentially hinder the implantation process?
