Could use some prayer

It has been a long road for baby number 1 my first pregnancy ended in a mc after only 6 weeks 2 yrs later finally got pregnant with my son so last October I found out I was expecting baby number 2 went to my 10 weeks appt only to find out I had a blighted ovum :( so I gave it a break and we decided to start trying in March well April I found out I was pregnant so tomorrow I will be 7 weeks I have started spotting and bad back pain so prayers that when I go in for my ultrasound tomorrow everything is ok!!!
