I slept with someone on March 31st and I missed my period in April. I took pregnancy tests and the end of that month and all came back positive. I cannot remember my period dates from march. Is it possible he is the father or was it too soon to cause me to miss my period?
Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Usually ovulation occurs around 13th to 17th day in case of regular 28 to 30 days menstrual cycles. If you are having regular menstrual cycles, with expected date of periods around middle of April, there is possibility that you might have ovulated at end of March and there is a possibility of pregnancy. To estimate the correct gestational age, you have to undergo ultrasound examination. This can give an idea of the date of conception also. To confirm the paternity, DNA analysis is the gold standard. Hope I have answered your query. Let me know if I can assist you further.
