Anyone ever think they were pregnant but found out it was a corpus luteum cyst.?

It is still possible you are pregnant. I myself have had two pregnancies that started like yours. Sometimes the hormones your body makes aren't high enough until 5-6 weeks along. With my second pregnancy I did several test before I got one that was positive. If you need to know check with your local health dept. You might be able to be seen there since you do not have ins. If you are than you will can possibly get covered by medicaid. I hope all turns out well :)
