confused conception

[wowsul94]

Hi all,

Massively confused, wondering if anyone could shed some light on the situation.

Recently discovered im pregnant, very pregnant (midwife suggested around 28-30 weeks from measuring my fundal height). However, I am pretty sure I conceived on the 9th January (25 weeks ago) and was only sleeping with my boyfriend at the time. According to the 'what to expect calculator' http://www.whattoexpect.com/toolkit/duedatecalc/duedatecalc.aspx   this would make me around 27 weeks 6 days gone. I haven't had periods for years due to medications so I can't use LMP here either.

I'm due to receive an appointment for a dating ultrasound scan within the next week or two,but have been told that due to the late stage of my pregnancy there is more room for error being able to calculate a due date.

Basically what I'm saying is, should I be worried if the dates range between 25 weeks ago when I conceived, and the 30 weeks that my midwife has suggested? I ask this because myself and the said boyfriend are no longer involved and I am worried that he might use this against me to try and escape the fact that it is his.

Any help would be greatly appreciated!
Thanks

My doctor told me the reason for an ultrasound at your first appointment is to tell how far along you are and the only way to no exactly how far along you are is to do one before 15 week. This is because after that point babies can grow at different rates and make it hard to tell how far along you are. For example say we both deliver our babies at 40 weeks and my baby is 6lbs and yours is 9lbs but yet they are the same age it is the same in the womb at 30 weeks my baby may be 3 lbs and yours may be 4 lbs so my best advice is wait until your baby is born and then if your doctor says the babies weight and health is perfect then assume you were around 40 weeks when you delivered and that will determine around when you conceived I mean your doctor should be able to tell your baby isn't full term

Thanks for your replies!

Don't want to have to go down the route of a DNA test, should have probably mentioned that in my post.

I must've ovulated, but my periods are so irregular that if I'd experienced spotting I probably wouldn't have thought it an issue.

The problem with my case is that me the father only slept together twice, which is why I'm so sure about when it must've happened. Scan tomorrow so we will be able to find out a due date then, an I guess I'll just have to take what they say as read about when the baby's meant to get here!

I would use the Dna thing if he says its not his. But.. really the most accurate for you I would guess is to.wait it out and see when baby gets here.

How have you been ovulating without a cycle? Not being rude but very very intrigued!!

You can always do a court ordered DNA test if he is difficult.

Well even if he tries to say it's not his just make him take a DNA test. I'd go off what your midwife is saying. The ultrasound will give you a better idea of a due date
