HELP!!

Jennifer

ok I had a miscarriage late October. had a normal period the 26th of November however the 19th I started a brown discharge then it stopped and the 21st I passed dark red clots and it lasted until the 23rd was not heavy just very clotted only when I went to bathroom it all stopped yesterday and turned dark brown again. my cervix is high and hard I had no cramps at all but for the past few weeks I have been extremely tired and boobs hurt feeling sick and cry at everything. tomorrow is when my original period was supposed to start. I have tried researching my symptoms but nothing is useful has anyone ever experienced this and what is the outcome I'm afraid to buy a pregnancy test and see if I was pregnant I'm just very confused and need helpful advice
