29 year old with Complex Cyst

I had a transvaginal ultrasound yesterday for weird cramping during my cycle. I had a miscarriage a year and a half ago at 9 weeks and at that time a roughly 3x3 cm simple cyst was found on my right ovary. Yesterday I was told a 2x2 cm complex cyst was found on my right ovary. I'm really scared as this month my boyfriend and I started TTC. We have no kids and hope to have some in the near future. I was told there is a possibility it could actually end up being a simple cyst but with the imaging it was hard to tell? Doesn't make sense to me. The following message is from my OBGYN after I wrote her with my concern after the visit. I saw a nurse practitioner at the visit instead of my actual doctor. "have looked at both ultrasound This cyst looks completely different than in past I don't think it is the same Todays sono looks like you ovulated We will repeat it to make sure it resolved I would like a repeat in 6 wks - lets do that instead of 8 wks- that way you are in a different place in your cycle Make that appt and see me that visit Hope this helps and don't worry - it most likely will resolve" The more I google (bad idea I know...here I am) the more it seems like complex cyst do not go away on their own... opinions?? Thanks
