How it can possible. Can sperm live in women body through MC and can survive and can make her pregnant. Please help me what is this? How it is possible? I m too much tensed. Please help me. She undergone through intra vaginal USG and in report doctor said she is 5 week pregnant The size of GS is 44 to 48 MM.secondary sac is seen there but no heartbeat is there he suggest us to come after 1 week to check heartbeat. If we count 28 jun as Last MP than she is 5 week pregnant,whose child she is carrying bcos i have not made any relationship in this month due to i was out of home. if on 28 jun that was not MC than it should be more than 7-8 weeks. Please suggest me what i have to do to clear this

dates for pregnanc are worked out based on the first day of your last MC. You are pregnant for 10 months total. Thsi sound totaly fine.
its confusing i know but so is everyone during a first pregnacy. 24 weeks is six months but you still have 4 months to go. its all strange.

It is a medical fact that sperm can live 5-7 days inside a woman before implanting an egg. It could also be that her dates are off a bit too. Just to give you an idea, I am currently 19 weeks pregnant according to my dating ultrasound with a due date of January 12th, but my last menstrual period was March 29, which would make me 22 weeks pregnant with a due date of January 3rd. Ultrasound dating is not an exact science but rather a guideline. A very interesting post to look at is this one:

It explains early fetal development and the markers they look for. Hope this helps.
