Marriage During OCIA

Hello all! My girlfriend and I are new to the Catholic Church. I grew up devoutly Protestant, drifted from the church and very recently renewed my faith and began attending Mass. Gf has a similar experience, but has not yet joined me in Mass but intends to. We planned on getting married in November 2026, but as OCIA begins this February and ends next Easter, I was wondering, is it valid for us to begin OCIA, get married, complete OCIA, and then have our marriage Convalidated and made sacramental? Any help and advice is appreciated, even the hard answers!
