Second lose and I don't know what to expect

Jenn

I just found out that I'm experiencing my second pregnancy lose. I lost twins at 8 weeks in March. I took Misoprostol to initiate the miscarriage (apparently my body isn't great at recognizing when I'm miscarrying) and experienced the most emotionally and physically painful day of my life. This time the lose is much earlier, exactly 4 weeks. I tested on Saturday when I was 4 days late and feeling definite pregnancy symptoms. I got a definite positive. Sunday I tested again and got a faint positive. Over the day I notice a decrease in symptoms as well. Yesterday I went in to get a blood test and they confirmed that my HCG was down significantly to 8.2. This morning I've started to see some brown blood when I wipe and I'm started to cramp. I've never experienced a natural miscarriage or one so early. Can anyone tell me what to expect? How painful do the cramps get? Do I need to super absorbent pads again? Should I avoid tampons and sex again for the next two weeks to protect against infection? Any advice would be greatly appreciated as I prepare to say goodbye to another baby that I'll never be able to hold. Thank you.
