I appreciate your query, but I would like to point out that there are a lot of gaps in the information you have provided..
For starters, I would like to know your menstrual history.
What was your LMP ( last menstrual period ) ?
Why did you get your B-HCG
I assume that your periods were overdue, hence you got it done to confirm your pregnancy
A level of 179 is indicative of a pregnancy, but only an ultrasound
can tell you whether it is intrauterine pregnancy or not.
You have not mentioned details of any examination or ultrasound report.
A falling value of B-HCG correctly shows that you had a chemical pregnancy, but not a clinical pregnancy.
In simpler terms, for you, it means that you missed the pregnancy.
Most probably, you should have had your period or some kind of bleeding recently.
3 follicles each of 1 cm in your ovaries essentially is normal.
Probably you were advised ultrasound to rule out ectopic pregnancy ( pregnancy other than that in the uterus
, commonly in tubes or ovaries ) .
But this is a normal ultrasound report.
No, based on this report, you do not have PCOS
PCOS by ultrasound is suggested when there are more than 10 follicles on each side, each measuring atleast 1 cm, and the ovarian volume is increased and the stroma is echogenic.
I am pretty sure this has not happened.
If you are trying to conceive, it is better to use protection till your next proper period, as your internal milieu needs to stabilize after a failed pregnancy.
Prior to planning any pregnancy, consult your doctor for a pre conceptional counselling
and start taking folic acid
Other medicines that you need to take will be indicated after your consultation with your gynecologist.
Hope this helped you.
