My period was due Oct 21, but nothing I had I miscarriage last month so I'm so confused well now for the past 9 days my boobs have been extremely engorged and sore plus I've been tired and haven't slept well! Also I've been very bloated. I just took a pg test it was negative so why do I feel like I'm pregnant again? Please help thank you

Could be a result of miscarrage and hormones coming back to normal levels, Could be the flu, could be you are pregnant, since this was too early to test, need to wait about another 5 days to a week.

Ty but I forgot to mention I'm waking up to pee all the time and I miscarried 9/30 please I'm worried maybe I should have waited because now I'm stressing wondering if I am or not, does anyone now?

Without doing the proper blood work, i.e. hcg levels, hormone levels, etc. we cannot give you a diagnosis via the internet. However, you mention that you did have a miscarriage on 9/30, so that will throw off your periods. You may miss one or two before they come back to normal.
