5 weeks pregnant but bleeding

Tomasa
Ok ladies I'm about 5 weeks pregnant was in the ER Sunday night due to bleeding. No clots just bleed like a period bleeding. Very very light cramps. And I was in the ER Thursday they did a HCG level check Thursday and it was at 29 Sunday it was at 84 since levels r going up they did nothing more for me and sent me home. I go for an HCG check later tonight (Tuesday 11/15/16) I'm super super nervous that this could be the start of a miscarriage but I'd figure I would've passed clots and or had really really bad cramping like all the others. I'm on bed rest till cleared by my OB
