5wks4days no fetal pole/Er docs said miscarriage

Hi all...I found out I was pregnant 2*12*13 lmp 1*14*13 4wks..I began to have mild cramps 2*17*13 common because I experienced this with my two previous pregnancies which were both full term..on 2*22*13 I began to really cramp w/o any bleeding but still went to ER they took blood my hcg was 2500 also did u/s an then told me the baby died no fetal pole an I would miscarry surprisingly I was ok then saw my Ob on 2*25 she said I should let it happen naturally. Had bloodwrk on this day also. On 2*26 @ 9a I got a call saying we need to see u ur levels are rising(3500) an we're gonna treat this as a normal pregnancy. Went in saw another doctor she said : could be twins, could be a miscarriage, could be to early blah blah right ..she checked me then did another u/s the tech kept asking had I ever had pelvic surgery NO ..then another doc discussed results : still no fetal pole just tissue an fluid no baby ..more bloodwrk on 2*27 another call on 2*28 my hcg is 5200 an I'm NW 6wks3days. They wanna do another u/s on 3*5*13 an said if they still see nothing then they'll label it a abnormal pregnancy at 7wks. I'm putting faith in the lord but their stressing me out I've had two healthy babies an never had a u/s til 14-15wks. I haven't cramped since 2*22 an haven't bleed since my lmp. I've had 5docs tell me so many things bottom line their all stumped. I want them to leave me alone no miscarriage symptoms. Has anyone else gone through this??
