Hello and welcome,
Please do not worry so much. Chances of getting pregnant from precum are extremely low and it occurs only in very special circumstances. If there was no ejaculation inside then the risk is almost zero. You have taken additional precaution of the morning after pill. So everything possible to prevent
pregnancy has been done. Do not worry. You will not get pregnancy.
Please remember to use condoms in future or some regular birth control measure like pills to avoid such incidences.
It is not advisable to take pills now to get a period. Since you have
irregular periods, kindly wait for at least 3 weeks from the date of the incident for periods. If they are absent, get a urine pregnancy test. Most likely it will be negative. In that case you may wait for another 2 weeks. If still negative you will need to visit a doctor and evaluate yourself for the reason of irregular periods, mostly
hormonal issues and then take treatment accordingly.
Hope this satisfies your query.
Thanks for using HCM.
Feel free to ask any more questions that you may have.
