Can having a blood pregnancy test right after your period affect the results?

Q. I am required to have a blood pregnancy test once a month for the acne medication that I am on, I recently had one about two days after my period ended and it came back 6.8 hCG. They told me this was a low positive...can having the test so close to the end of my menstral cycle affect the results?

A. Pregnancy Tests and hCG Hormone Levels

As noted on our products page, our pregnancy tests detect the hCG hormone. Because hCG is secreted by developing placental tissue, it's very reliable indicator that a pregnancy has taken place. One of the most common customer support questions we receive is: "When can I begin testing for pregnancy during my cycle?" To understand when, let's take a look at the general timeline of events that take place once ovulation occurs. As noted above, when conception (the meeting of egg and sperm) takes place, the embryo is still "free-floating" in the space of the mother's womb. hCG only starts flowing following implantation. Typically, implantation of the embryo takes place a handful of days after conception - around six days or so on average. Once the embryo implants, hCG is rapidly produced and doubles in early pregnancy every two to three days. Hence, the rate in which hCG increases is very rapid, nearly exponential. This is called hCG doubling time.

With 20 mIU/ml/hCG pregnancy tests (high sensitivity), you can typically begin testing at around seven to ten days past ovulation. On average, this is when the hCG level in a woman's urine starts to exceed the 20mIU/ml/hCG threshold. Do note that "average" does not mean "everybody"! A negative test result this early in pregnancy (7 to 10 DPO) is not necessarily conclusive: hCG develops at different rates among women, and for some women hCG develops slowly. Follow up tests are recommended every 24 to 48 hours using a first morning urine sample. First morning urine will yield the highest volumes of the "pregnancy hormone". Once you determine a positive result on a home pregnancy test, follow up with doctor.... and congratulations!


So far sounds as if you just got pregnant, The egg may not have implanted yet and is now moving to the uterus. The hormone does double every 48-72 hours so give it a few days and try a pregnancy test. Or make a doctors appointment, to receive a more sensitive test.


Am I overly emotional because of the pill or could it be pregnancy?
Q. I'm on the pill and lately I cry at the drop of a hat. I've read on the internet that this is a sign of pregnancy so I'm a little freaked out that the pill didn't work (I just started). Is it more likely that this emotional state is caused by the pill or by pregnancy?

A. It's really a toss up and depends on a lot of things. Also, the pill isn't 100% effective. My guess is that the pill wouldn't be effective right away, so it would depend on the timeline of when you started the pill and when you had sex. You could wait it out or take a test, but if you don't want to be pregnant, I would say use a condom along with the pill!


Had period on July 24, is it too soon to start feeling symptoms of pregnancy?
Q. I've been feeling sick for a couple days now, food is just gross to me, but not all day like it normally would if I were sick. Just off and on. Last time I had no morning sickness at all, and I know things change from pregnancy to pregnancy.

A. need a bit more info but the answer is no it is never too soon. With my first two (16 and 14 years ago mind you) I felt pregnant after fertilization... But let's look at your timeline....

From what you said....

July 24 first day of period
Aug 6 roughly time to ovulate for a 28 day cycle.
Aug 12 -18 technically time of possible implantation (it is when feelings of pregnancy could be felt)
Aug 23 no period could be pregnant.

There are no guarantees that you are pregnant but I would act as though you were. Think positive and enjoy the two weeks.

I felt pregnant had symptoms like yourself, however for me it was negative I got my period today....

Good luck with it


Any ideas where I can find a canine pregnancy calendar online?
Q. I have found one before where you tipe in the date she was bred and it gives you a timeline of what to expect and an estimate on the delivery date......

A. There is a link for the calculator at the bottom of this page:
