Hi... I am new on here. I have a few questions, but Ill tell you my story first. I am 21 yrs old and have a 4 yr old. I was told back in jan. that I have endmetriosis after not having a period for a yr, and cyst all the time since Oct 07.They told me not to plan on having anymore kids because my ovaries we so bad.They would swell up to the point were I couldn't move. I had an appointment to talk about getting a hysterectomy, well I had had not had a period since June 23. So I decided to take a test , just in case. Well it was positive. We are super excited. Well I have been told that I am 13 weeks. Well I had to go to the ER this morning for really bad pelvic pains and some spotting, and they said I have cyst again. But they also said I am only 6 weeks and 6 days pregnant. They said the baby was doing great and the heart beat was great. But there is no way I'm only 6 weeks. My last period started June 23 ended June 31st. Two weeks later I spotted for 2 days and nothing since. But I know I am more then that because my husband and I didn't have sex in August ,because it hurts me to bad. We may have had it a few times in July ,but not very much.So we are both very confused. The least I could be is 9 almost 10 weeks. Could they be off by that far? Has this ever happened to anyone? I am just so confused. I have a doctor visit on the 1st but I wanted to ask some people before then. Sorry this is so long. If anyone has any answer please feel free to reply.:rolleyes:

Also my cycle is always 21 days apart and have been since I was 16.

Well they are not always accurate with due date, it is just an estimate, but I have never heard of them being off by so much. Its usually by a week or so.

Due date estimates this early can be off - but I'd have a hard time thinking they were off by 3 weeks or more because the fetus looks very different from 6 - 9 weeks development.

If you're periods are not consistent that could be why your dates are off. Some women have periods even when they are pregnant as well. Is there a chance you're forgetting a time your husband and yourself were together? Another possibility: Sperm can live up to 5 days before your egg could be fertilized.

I don't know.. I guess I'll just have to wait and see what they say at my appointment. I got to thinking ,maybe he read it wrong. But I don't know...
