As you have PCOD, you are likely to have progesterone deficiency
naturally. You are being given these medications to maintain pregnancy
and to avoid any threatened abortion
. Your sonogram report shows normal findings and in the absence of exact dates of menstruation
, the sonogram dates would be taken as standard. It is too early to comment about the mode of delivery but cephalo-pelvic disproportion (CPD) may recur in the next pregnancies also. You may consult your specialist for further suggestions. Good luck.
