Thanks for writing in.
It is always good to take recommended dosages of medicines. Most likely there is no chance of a pregnancy
happening. The normal hormonal
balance to help in the implantation
of fetus is altered and so please do not worry.
To confirm please get a home pregnancy test done. This is very easy and safe.
Sex withdrawl method is not as safe as thought earlier. I recommend using condoms for safe sex and to prevent STDs and HIV
Hope this helps.
