Waiting for a miscarriage...

Two weeks ago at my 8 week ultrasound we found out our baby was not growing. Last week we made the decision to wait and let my body naturally have a miscarriage. I'm still waiting and it's the worst waiting game ever. Today I woke up with a migraine which I take prescription medication for. While I was pregnant I had to stop taking the medication. I'm struggling today with what to do. I know this isn't a baby I will ever deliver and meet but since I haven't had a miscarriage yet I'm wondering if it's ok to take the medication or not. I feel horrible but I just want this over so I can begin to grieve our actual loss and attempt to move forward. For you ladies who have unfortunately been here - what did you do while you waited for a miscarriage to occur? Last night my husband even tried to convince me to enjoy a glass of wine with him and I didn't know if I should. This is all just so confusing.
