I had unprotected sex 20-25times in 2 days as i was ovulating and a week after a cyst removal. only precum entered me each time. can i be pregnant?

Pregnancy: Yes....anytime you have intercourse you have the chance of being pregnant. Pre-ejaculate has sperm in it as well as the actual ejaculate. It only takes one sperm to fertilize the egg. As far as your surgery and cyst removal goes. I am not sure where you were in your cycle and what type and number of cyst you had so I can not commenting that except it is very early to have intercourse after
