I usually have a pretty normal cycle. Lasts about 5-6 days every 28 days or so
The length of your cycle also needs to b taken into account. My cycle is ever 33 day dr use an estimator with 28days
Thanks. Makes me feel a lot better and still going to talk to my doc to get another opinion
Google "conception calculator" and enter your due date and it should say when you likely conceived. Based on the due date you gave above I checked for you and it says you most likely conceived between January 2nd-January 10th. Hope this helped!
Talk to your doctor! Just for fun me and my boyfriend asked when she thought i conceived and she gave us a few dates it would've been!
It is more likely you conceived with man b but definitely talk to doc for their ideas and honestly if man a isn't around does it have to matter just let man b be dad if he is ready and everything.
