Bleeding in pregnancy.

So Ive had 2 live births, and 2 misscarriges. Im Now pregnant again after 3 months from my last misscariage. I had light pink spotting and went to the ER. Levels were good, ultrasound was good baby had a heart beat of 126. Bleeding stopped. The next day later in the day I had bright red bleeding like a light period and went to the ER again. They said there is more bleeding than what they'd like to call just implantation bleeding and a blood clot. My levels did go up but because I was only there yesterday they cant really do much. They wont repete an ultrasound to see if the heart beat is still there. 🙄 Does anyone have any postive expierences with this and baby was fine? Wont get an ultrasound until monday.
