Hi doctor,

We had sex on her fourth day of the period. She took an I-pill within two hours. She got bleeding after five days. Today is the 27th day after sex, she got some nausea at noon, but no other symptoms. She got an I-pill previous month. Is it the temporary hormonal problem or she might be pregnant? Can she use pregnancy kit now? Please help. 



Welcome to icliniq.com.

  • Sex done on the fourth day of the cycle is entirely safe and has no risk of pregnancy.
  • This effect could persist for six to eight weeks after taking the last pill.
  • Just be relaxed. You need not to do the pregnancy testing.

Thank you doctor,

She still did not get her periods, but having period like symptoms like lower back pain. She did her pregnancy test through home pregnancy kit. It was negative. Is there any chance of pregnancy still? What should she do now or when her period will come? As mentioned the previous bleeding after takings I-pill lasted only for three days. Is there any possibility of being pregnant? Please help.



Welcome back to icliniq.com.

  • You have to keep faith in the medicine as well as science.
  • There is no chance of pregnancy if there is sex on the fourth day of cycle irrespective of I-pill use.
  • But, there might be a delayed cycle as I have told you, which could extend up to six weeks.
  • There is no way that you can induce her cycle now. Just console her and ask her to be calm.
