Romero started playing basketball in local clubs from the CB Agüimes, Baloncesto Telde and de CB Islas Canarias, where she made her debut in the Spanish top tier league in 2010, at only 15. She spent three seasons in the senior team, averaging 8.4 PPG. In her last season in the club she averaged 14.9 PPG, 3.6 RPG and 3.5 APG before turning 18 years old. In the 2011 and 2012 seasons she played a total of 16 games in Europe's second tier tournament, the EuroCup.
U.S. college career
Romero, a native of the Canary Islands, was widely sought after by major U.S. college programs going into the 2013–14 season, ultimately choosing to play at Kansas State largely because of her rapport with the coaching staff. At the time, she was not fully comfortable with English, and according to ESPN journalist Mechelle Voepel, was "seeking a place she would feel taken care of and safe". While the Wildcats only finished 11–19 in her freshman season, she enjoyed considerable personal success, averaging 14.2 points, 5.8 rebounds, and 5.0 assists per game on her way to being named unanimously to the Big 12 Conference all-freshman team and also earning second-team All-Big 12 honors. Shortly after Romero received a release, she received a call from Sue Semrau, head coach at Florida State, one of the schools she had visited during her original recruitment. The two quickly reconnected, and as Romero considered her options, she found herself drawn to the Seminoles' style of play and willing to meet the expectations Semrau was setting for the program. She then enrolled at FSU, initially planning to sit out the 2014–15 season due to NCAA transfer regulations. Given the situation surrounding Romero's transfer from Kansas State, Florida State petitioned the NCAA for a waiver to allow her to play after the end of Kansas State's 2014 fall academic term. Semrau had told Romero that the chances of a successful petition were low. Since Romero could not travel with the team as a redshirting transfer, she went to her home of Las Palmas for a short Christmas break. During that time, the NCAA granted the petition, allowing her to immediately play for the Seminoles. Despite missing the first 13 games of the 2014–15 season, she was second on the team in assists, also averaging 10.1 points and 5.3 rebounds in the regular season while being named to the all-Atlantic Coast Conferencesecond team.
