😥sac or too early?

Mollie

Would you say this is a sac or not? I have been getting positive tests for a week now and I thought I was around 6 weeks from my calculations so I went got a vaginal ultrasound and the tech said she can’t work out weather this is a sac and I’m way too early as I have pco’s and I could of ovulated later or she said this could be a pregnancy of an unknown location so back for blood tests tomorrow so they can figure out what’s going on 😔

My clear blue digitalis have been reading 2-3 weeks and 1-2 weeks for the past week now constantly changing which I know isn’t a good sign either 😢
