Just get a few more blood tests for beta hCG. When, or if, that level reaches about 2000, you should be able to detect an intrauterine gestational sac with transvaginal ultrasound. Baby might not be seen yet though. The cyst could be the corpus luteum which will most likely resolve.
U should be ok I had something similar as to a right pain and spotting on and off an entire month I was 8wks 4days along in my pregnancy when I found out and now I'm 28 wks pregnant with healthy bbygirl.....good luck
Give it some time if you just got a positive on a home test it can take up to after 8 weeks for them to see the baby on a ultrasound bc it's so little I will be sending prayers your way try not to stress to much goodluck and keep us posted
