Hi Misty H.
I just found out I'm 4 wks and 4 days preggo, and I have a cyst of 5cm, my Dr said the same thing if it does not get any bigger then there would be no need of a surgery since the baby is still so small I would have to wait till my 14th wk to remove the cyst if it did begin to grow I know how you must feel I haven't been able to conceive for a long time this is my first pregnancy I'm hoping all goes well and the cyst disappears. I wish you all the best as well .
Every pregnancy I've had (on my 3rd) has begun with a cyst found on my ovary. They are normal for some women, as long as your doc is monitoring it and the pain is tolerable, you should be ok. Trust your instincts and your doc and don't put too much energy into it . . . Good Luck :)
