Hello sir I have a question regarding my menstrual cycle. Me and my boyfriend had sex without protective measures but never had the last moment withdrawal or nor he did it inside but the problem is my cycle is late by 10 days. One more thing is I had consult a dermatologist who gave me a tablet for which she said if you are having this tablet means you will have problem with pregnancy. And I had tablets for allergy also. Will it be because of tablets or pregnancy.
