baby, are you saying he and she split up after she put a baby up for adoption that was not his? Or that she put up a baby for adoption that was his? If the first, there are other possibilities besides that he had fallen in love with the baby and was sorry it was gone (unless, of course, he told you that was it). It's pretty rare for a man to want to raise someone else's baby. Maybe there was stress in the relationship because of the pregnancy, or just in general.
Adoption is a great option but men fall in love with a baby during pregnancy wait and see how he acts before choosing. My brother went through this and him and her split up a couple of months after the adoption I think it depressed them both.
Yes its January 18.I will do the test. Thanks for the reply its giving me a peace of mind. Because I might consider adoption if the baby is not his.
Here is what the conception calculator says for the first day of your last period of April 13:
First day of last menstrual period: April 13
Probable date of ovulation: April 27
Possible dates of conception: April 23 to May 1
Due date: January 18, 2014 (40 weeks)
If they told you something different than January 18, let me know, and we can count backward from what they said.
Sonograms are rarely off by even a day when you're 6w5d gestational age. Keep in mind that the medical way of counting gestational age (GA) begins the count on Day 1 of your period, not on your conception date. This is a medical convention harking back to the days when the first day of the woman's last period was the only thing they had to tag any kind of timing to, and it has maintained even to this day and age of ultrasounds. Your ultrasound measured your embryo, counted forward 38 weeks to get a due date, and counted backward to get an estimated first day of your last period. If it gave you January 18, I'd say you were in your third week of pregnancy (counted the GA way) or your first week of pregnancy (counted by conception) when you had the fling. Get a DNA test to be sure once the baby is born, but unless the dates here aren't adding up, you're probably in the clear (admittedly not by a huge margin). Incidentally, if the sex with the ex was unprotected -- you know what I'm going to say, right? Get tested for STDs at one of your prenatal appointments. You never know.
If the dates I'm saying add up, take it as a working hypothesis with a lot of support, that your boyfriend is the dad. That said, a DNA test when the baby is born will put all worries to rest. Congratulations!
