when to go to ER?

Chelsea
I'm so confused, currently going through my third m/c. Blighted ovum diagnosed at 7 weeks, at 10 weeks decided to take misoprostol to jumpstart things, because I was feeling SO sick still and couldn't emotionally handle it any longer. With the help of the pills I started bleeding may 23. The first 24 hours were pretty heavy, then died down for 2 days, then a few more heavy days, back to very light.. this has been going on since the 23rd and this morning I passed a very large clot/chunk of tissue. I've been having very steady bleeding and bad cramps since this morning. Really trying to avoid the ER since my husband is still out of town.. but starting to wonder if I should go in?
