Hi congrats !
U may be having delayed conception.I hope u have met a obgy and got yourself checked.sometimes there may be a hormonal
support needed especially in case of pco who are pregnant.there is no need to panic u can follow the pregnancy
with a fetal viability scan after 2 or 3 weeks.also check with your obgy n whether you need any supportive hormones. Have patience and think positive. Goodluck to you.
