Hello I didn't have sex but semen could have possibly come in touch with vagina during make-out on 24th November. She took Susten 300 (prescribe) around 15th October and periods started in 3 days so she stopped taking medicines after 3 days as instructed. She again waited for her periods to come normally but when it did not so she had her medicines again from November 28th November for 10days that is till 7th December. It's been 4 days after that and she isn't getting periods. Could she be
pregnant? When should she check for pregnancy, what should she do to check? If she's not, why isn't she getting her periods like she's usually does after taking her medicines.
