I figured that's how it worked. I just saw some of the online due date calculators, and they never seem to ask about your cycle length. </p> https://boards.hellobee.com/topic/question-about-long-cycles#post-125082 Mon, 16 Apr 2012 15:20:03 +0000 Mrs. Train 125082@https://boards.hellobee.com/ <p>The best way is to have an early ultra sound. They will measure the embryo and give you a date. But if you try to guess like mrsjwy said use your ovulation which is two weeks before you get a positive pregnancy text</p> <p>I had long and irregular cycles. They were anywhere from 35 to 90 days. When I went to the dr I tried to tell the nurse but she wasn't paying attention. She took the date of my last period and wrote it down. By her calculations I was 13 weeks pregnant. I told her I knew that was not the case and that I was probably six or seven. She still wouldn't listen. The dr came in did the ultra sound and I was six weeks pregnant. So just remember to kept reminding them you have irregular cycles </p> https://boards.hellobee.com/topic/question-about-long-cycles#post-125071 Mon, 16 Apr 2012 15:13:40 +0000 chopsuey 125071@https://boards.hellobee.com/ <p>My cycle is all over the place too since I'm still nursing. I think O dates are usually 2 weeks before you get your BFP though. </p> https://boards.hellobee.com/topic/question-about-long-cycles#post-124997 Mon, 16 Apr 2012 14:56:40 +0000 mrsjyw 124997@https://boards.hellobee.com/ <p>My cycles average 36 days. The way that I calculated my EDD before drs appt was based on my "O" date + 2 weeks prior being pregnant. The dating U/S confirmed my date when it measured the fetus. </p> https://boards.hellobee.com/topic/question-about-long-cycles#post-124988 Mon, 16 Apr 2012 14:54:02 +0000 futuremama 124988@https://boards.hellobee.com/ <p>Purely hypothetical, but I'm curious. I know that generally your due date is determined based on start of your last period. However, my cycles are all over the map (been off of BC for 3 months). If I happen to get pregnant during a cycle like last month, which was 55 days, do they use a different method?</p> <p>Hopefully I'll just get back to my normal, pre-BC 28 day cycles though! </p>
