### input:
I am 19 years old and I indulged in unprotected sex about 53 hours back. The guy pulled out before ejaculating but we are still unsure of the circumstances. I am a case of PCOD which is why menstruation cycle keeps changing and I have been taking medication for that since a year and I have also been taking medication for my skin allergies regularly,homeopathic and allopathic. Is there any way I can know for sure whether I m pregnant or not,also is it advisable for me to take a contraceptive pill like I Pill before 72 hours are completed ?

### output:

Hi there, My opinion after reading your question is that:1) After having unprotected intercourse, it is better to take an I-pill within 72 hours. This is to be done even if there was no ejaculation because pre-ejaculate also contains sperms.2) I do not know what treatment you are taking for POD, but if you are taking oral contraceptive pills like Yasmin or Ya mini or Male D or Duoluton-L, then you do not need to worry about taking I-pill. This can be determined by how you are taking the medicines. If you are taking 3 weeks of medicine followed by one week break, then they are most probably oral contraceptive pills.3) There is no way right now to find out if you are pregnant so soon, you will have to wait at least for two weeks and then get a blood test called serum beta Chat Doctor. If you miss periods, you can get a urine pregnancy test done.4) So to sum it all, I think you should take an I-pill as soon as possible. Then you can wait for periods. If you get them, nothing to worry. If you do not, then get a urine pregnancy test done. I hope this was helpful.
