Hello and thanks for your query.
I shall make an effort to provide you with good professional recommendations specific to your questions.
After consuming the post coital pills, your next period should start within the next month, although it might come a few days early or late.
Post coital pills are highly effective taken within 72 hours of
unprotected intercourse. As you have consumed within that time, you are less likely to be pregnant.
It's best to do the home
pregnancy test first thing in the morning, when your urine is most concentrated and
hCG levels are highest.
So I advice you to perform a test a week after missed period and with morning sample of urine. This test kits are nearly 98% accurate, so reliable.
Irregularities in menses is quite common in females with
PCOD, it need to be treated, so advice you to see OBG specialist.
I do hope that you have found something useful to help you and I shall be glad to answer any further apprehensions.
Take care.
