Hi, I had gone through your question and understand your concerns. More likyl father is the one that you had intercourse with during the middle of your menstrual cycle. If both inercourses were during this period then no one can tell you who the father is without genetic testing which can be done in speciliazed centres. It would be good that you do this as soon as possible so that father can be informed about this and further plans discussed with him. PAternity test usually must be paid and your local GP would have more info about the possibility to do it in your area. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
