I am 10 weeks PP and think I may possibly be pregnant. I delivered my daughter on June 27th and bled till about July 20th. So I really don't have a "last period date" to go by. I would have conceived on August 11th it's the only time we didn't use protection and we just did pull out twice that day. What are the odds? I know the speech on how fertile I am and blah blah just curious of anyone can help with dating and if it's possible
