Cramping at 10 weeks

I feel sharp pains on both sides at 10 weeks. It’s been constant for two days. I have doctors appt and ultrasound tomorrow but I’m nervous something more is happening. I’ve read it could be round ligament pain but idk if I believe it.

I do have a yeast infection and was taking terazol. She told me to stop taking it immediately.

I also stupidly used a fetal Doppler for reassurance and of course no fetal heartbeat was detected.
