Should my period be late while taking Metformin?

I have been on metformin for PCOS since October of last year. After getting married in December I would miss taking it sometimes. But since being on metformin I have had regular cycles every 28-29 days. So im very confused I am now on day 35 and still nothing, some symptoms but nothing. Did I mess up my body with missed dosages or could I be pregnant? My husband and I have been TTC since December but I'm too scared to take a PT and be disappointed.
