Help ???? About HCG levels

Jessica
Ok so I took my first pregnancy test on Monday which was negative took another one on Tuesday they were all positive confirmed by urine and blood by the doctor my hcg level day was 63.4 I went to the OB that Friday hi my levels done again and they were 170.8 question is are those ok levels so about how far along do you think I would be because I have PCOS and I'm always a week behind or at least a few days so at this point I have no idea when I ovulated I'm thinking the 14th because my actual ovulation window by this app was the week of the 4th and 8th but I think with me always being a week behind actually think that'll put my fertility window the week of the 14th so I actually have no idea when my due date is does anybody else have a good guess
