Well this is what i am saying she knows she had sex on the 26th of nov and her period was nov 15th the last day of her period and then she had a 2 day period on the 15th of dec now if i am right she concived on the 26th or a few days later right? And her Dr is trying to tell her that she is only 33 weeks preg, but she has been having horriable contractions and has lost her mucos plug and the baby is far down that the dr said she can feel the head but told us that she is not dialated and her cervics have not thened. She has only had sex one time and that was on the 26th of nov. Please help me i want to know is there any way the dr could be mistaken or am i just worried about it. I am my nieces Foster Mother. Please help. Thank you
