Do you mean day 28 since the first day of your last period or do you mean day 28 since the day you conceived? If you mean 28 days since your last period, then yes. If you mean since conception, possibly, but implantation/bleeding usually happens within 1-2 weeks after conception.
This may be implantation bleeding if it's light. If it gets heavy, you need to call your doc.
if it is light that is one thing go to the doctor either way, it may or may not be serious
you have your period
go to the doctor dummy
Wth is a "late" conception? Do you mean at the end of the fertile period? That would be irrelevant. Conception, not fertility is the start of pregnancy, so heart beat begins roughly two weeks after conception. Late has nothing to do with it.
If you mean 4 weeks after conception the embryo is about 1/6 to 1/4 inch (4 to 6 millimeters) long.
Implantation bleeding usually occurs around 6-12 days after conception, so having it a few days later than usual is less likely to be implantation bleeding. The negative HPT results at 2 weeks after a light and short period suggest it may not have been due to pregnancy. If you are concerned, it is best to consult a healthcare provider for further evaluation.
It is possible that this isn't menstruation at all. Light bleeding mid-cycle may be ovulation bleeding or hormonal imbalances causing spotting. If it's a one-off then it's nothing to be concerned about, but if this occurs on a regular basis it is best to talk to your doctor about investigating the cause.
Go to the hospital! I don't mean to scare you but it can mean a few different things.... 1. your amniotic sac (what the baby lives in) separated from the uterine wall 2. miscarraige 3. It could be normal bleeding CHECK WITH YOUR DOCTOR ASAP OR GO TO THE ER! BLEEDING DURING PREGNANCY IS NEVER GOOD!
The earlier it is the more accurate it is whether from conception or from LMP, but if you say 12 weeks you mean from LMP.
No. Your due date is calculated from two weeks before actual conception. You are actually pregnant for 38 weeks. You conceived 18 weeks ago.
