[blueeyes92]

So I went to my first doctors appointment the 8th of April I found out I was pregnant the 31 of march my last period was Feb 1 st my doctor is saying my due date is Nov 24th and the cacultor pregnancy thing is saying that if I'm due Nov 24th my last period would have been the 17th so I put in my last first day of my first period and its saying Nov 8th idk which one to go with plus I have another question. I had sex with a guy toward the end Jan and had my period Feb 1 had sex with my boyfriend on my period  and then never had my period in march would the second guy be the dad???

What I think is going on is that you are counting backward all the way to 0 when you are computing the "weeks pregnant" date, because the doctor said you were a certain number of weeks pregnant.  But, when a doctor uses the weeks count, he or she is computing from the assumed first day of your last period, which would have been around February 19.  That is the middle of the month as you have been saying.  But it does not point to the date of conception.  Medical counts of "weeks pregnant" count back to the first day of bleeding of the period, or if a woman has irregular cycles, the computed first day of last period, and ovulation and conception don't happen then.  The woman is having a period, she's not pregnant, but that is what date they use to begin counting even so.  Ovulation and conception happen two weeks after that.  If a doctor or nurse or tech (anyone medical) looks at the embryo on an ultrasound and says you are 7 weeks 2 days pregnant, he or she means you are 5 weeks 2 days since conception.  All that your doctor said, the due date and the 7 weeks 2 and the April 8, all tie in to you getting pregnant (actual conception) around March 3.  Depending on how late you had sex in February, it sounds like the wrong guy might have been too early to produce a baby, since sperm only lives about 5 or 6 days in the woman's system, if any escaped his urethra in the pre-ejaculatory fluid in the first place.

When you went to your appointment on the 8th, did they do an ultrasound then?  What is an estimated ultrasound?  They did an actual ultrasound and gave you the due date of November 24 from the information learned in the ultrasound?  And that was on April 8?  Was that when they said you were 7 weeks 2 days?

When I went in they did an estimated ultrasound of baby of how far long I could possibly be at first when I went in before ultrasound they based it of my last period witch was Feb 1 and said due date was Nov 8 then said Nov 24 but I go to a hostipal that ain't that bright they recently messed up on my sisters due date so I'm going to find a different doctor and see if they change due date. Sane happened to my second son got told so many due dates. Idk these is stressing me out cause I don't want it to be frisr guys want it to be second guys.

No on the 8th of this month I went to my first doctors appointment and I was told then that I was 7 weeks 2 days.

Who said you are 8 weeks 4 days, not the doctor on April 8, right?  Because if he told you November 24 was your due date, he would not also have said you that you were 8 weeks 4 days GA on April 8.

No I sleep with only my boyfriend from the begin of Feb to the end. I did however see someone towards the end of Feb but he never got off in me. I do however believe it it the guy I'm with now well my boyfriends baby. Cause when I add time back it doesn't add up to be even close to his they say I'm 8 week 4 days and that's would have made me be pregnant towards the begin or middle of Feb and that's when I've been with my boyfriend

Was it from an ultrasound that the doctor was telling you the due date?  In other words, did he see the embryo and get measurements?  Don't let a calculator saying that your period was off the track make you think an ultrasound was wrong.  The ultrasound sees and measures the actual baby.  Your last period could have been a year ago and the ultrasound measurements of the embryo would still be exact.  

If the doctor told you the due date of November 24 based on some other data, then you need to get an ultrasound.  It's early days yet in your pregnancy, and this would be the right time to get one for the purposes of determining conception.

Did you sleep with anyone in late February or early March?  I'm not getting, from ANY of the dates in the story including the ones you calculated from the first day of your last period, that the guy in January before your last period is a problem.  But if you had more partners than your boyfriend in February, you might have some figuring to do.
