Praying for a miracle!!

I’m 7 weeks today and yesterday I started spotting some brown discharge then It went to link to red with blood clots. I went to see my OB and they did an ultrasound and only found a sac no fetal pole yet. He said he thinks I may be earlier than I thought and had me to labs to check my hcg which were 2284. He said to come back every 48 hrs to see if my levels are doubling. Well this morning I had severe cramping and another blood clot and heavier bleeding so I went to the ER. They did an ultrasound and same found a sac but no fetal pole. My hcg was 1324 today. Again the doctor said either I’m too early to see baby or it could be a possible miscarriage. They want me to do my labs every 48 to see if they rise. I’ve had 3 miscarriages in the past so we thought this was our rainbow baby. Praying we still have a chance! ❤️😭
