5wk 2day ultrasound...no baby just sac

Brooke

So today I had pretty intense cramps on my left side so I went to the ER since they wouldn’t go away (still kinda bothering). They took urine that was fine, took my blood which increase from 3,055 on Monday to 7,000 today, and did an ultrasound. They could only see the sac which was measuring at 5 weeks and 2 days. She said that was normal and that you can’t see the baby until 5.5-6 weeks. Do any of you mommas have cramping? They said I have a yeast infection and a bacterial infection (which they can’t treat until 2nd trimester)

Also the ultrasound says 4w 3d because that’s based off my last period but the sac measures different.
