Corpus Luteal Cyst

Tay

I’m guessing this is the same as Corpus Luteum cyst? I had an ultrasound yesterday and it said I had one on my left ovary. My period is due today. I’m experiencing a lot of bloat and cramps today so it should be here soon. I took a pregnancy test and it tested negative. I had sex on one of my fertile days. Not sure if it’s too early to test. I heard a corpus Luteum cyst can come during pregnancy or when your period is due. So I didn’t want to get my hopes up. Thoughts?
