Hello and welcome to HCM.
Thank you for your query.
I can understand your concern and shall address your queries one by one.
Starting off with your first query, PCOS can be diagnosed clinically with the help of symptoms, but still requires a confirmation using an utrasound, which I advise at the earliest.
PCOS is a purely
hormonal condition, thus affecting women in the reproductive age group, so the c-section would have nothing to do with this, but a hormonal imbalance could easily cause this.
The morning after pill has a known side effect to cause irregular bleeding and a change in the usual menstrual cycle, but to an extent equivalent to almost no period without medication, is usually not seen with the morning after pill. This could purely be a hormonal imbalance, and if the PCOS diagnosis is right, this could be directly attributed to the condition.
The more extensive testing you are talking about would include hormonal levels:
estrogen,
progesterone, testosterons, DHEAS, etc; along with an
ultrasound to confirm the suspected diagnosis of PCOS.
Now coming to some extra information,
metformin is advised in women diagnosed to have PCOS, for two purposes:
1. Normalize/regularize the menstrual cycle
2. Loss of weight (in woman who are slightly
obese)
If you indeed have PCOS, and have noticed an increase in weight since the time when your cycles were normal, this could also be attributed to the weight gain. PCOS gets worse with weight gain, if you have put on weight, I would advise losing it.
It is difficult to calculate your day 1 right now, as your periods are very irregular. Let us wait till your periods are normalized, and then calculate the day 1.
I would also like to add, that metformin, birth control pills, hormonal supplements, etc; will all be used to normalize your period. Women with PCOS require a certain medication to help conceive (
clomiphene), so this will be initiated only once your period is regular again, only once this is initiated, can you successfully conceive.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications at: http://doctor.healthcaremagic.com/doctors/dr-shoaib-khan/64581 . I would gladly help you.
Best wishes.
