the bleeding isnt that bad ive lost two babies in the past and its alot less blood than before my progesterone levels are low too i think 4 the first time then they went up to 6.5
well they dont actually need to double, the need to rise by 60% every 2 days, hcg levels do vary from pregnancy to pregnancy and women to women, the levels also have to start somewhere as well they just dont start in there thousands so as long as they go up by 60% next bloods everything should be fine. Progesterone only works if thats low, if your going to miscarry due to other reasons it will not save the pregnancy, has your bleeding settled down, alot of women have differnt types of bleeding early on as well and go on to have healthy pregnancies as well good luck
