Could Delayed Period While Having Ovarian Cysts Indicate Pregnancy?

Hi. I have had ovarian cysts off and on for a little over a year. And each time I have had them, they dont pop untill i have my period. Well me and my husband are ttc and i have a lot of nausea and vomitting- BUT i get that from my cysts too- Well yesterday my cyst popped and still no period. Is there a good chance I could be pregnant?
