Brief Answer:
yes, with genetic tests

Detailed Answer:
Hi and welcome to HCM.
Without tests there is no possibility to know who is the father considering such short interval. So there are tests where amnion fluid from your uterus is taken and blood samples from both partners. then these samples are compared and genetic tests are done which are 100% reliable. Another option is to wait till birth and then take babies blood sample. Wish you good health. Regards
