Hcg levels at 4 weeks 4 days where 1300 does this seem like a high number i know its hard to tell from a single test waiting on results of 2nd test?

As you said: Hcg levels vary significantly. Repeat test is critical to determine an appropriate rise. You are on the right path.

HSG Levels: Hcg levels rise throughout the pregnancy. I assume you are saying 4 weeks 4 days from the last menses. The levels of HCG double approximately every 48 hours. Therefore, the level may be normal. Sometimes a "high" level may indicate multiple pregnancy, getting the dates wrong or a normal pregnancy. I would get an ultrasound at 5 weeks assess the pregnancy.
