6 weeks and 2days

Janae

Pregnant and have been having some bleeding on and off for a minute now. Light bleeding. Got my hcg levels first they were 2714 and then two days later they dropped to 2590.6 and then they shot back up to 2864. Im worried because I never experienced any of this with my first two kids. Should i be worried? My first ultrasound they seen the sac but it was empty told me it might be too soon and my sac was measuring at 4 weeks then. Should i be worried?
