But even if the fact of pregnancy is already established, many women do not hurry to hide the thermometer, and continue to regularly check basal temperature. For what they do it, or what the graph of BT on the initial stages of pregnancy can tell, let's find out.
The basal temperature chart for early pregnancy: the norm
Girls who are actively planning pregnancy, it is well known that in the second phase of the menstrual cycle, the basal temperature rapidly increases to a mark of 37 degrees. If fertilization did not take place, then a couple of days before (and sometimes on the first day) monthly temperature drops to 36.8-36.9 degrees.
As a sign of pregnancy, it is possible to regard invariably high BT values (37-37.2 degrees) throughout the second phase, including in days of delay. Whether the schedule has deceived, it is possible to check up some days after a delay, having handed over the analysis on hCG or having made the test.
If the pregnancy is confirmed, then the normal high basal temperature will last for another four months. Although its indicators will gradually decline after 4 weeks.
Disturbing symptoms
Girls who before the onset of pregnancy kept a diary of BT, doctors strongly recommend continuing measurements. As temperature values can notify about the begun pathological processes. So, low temperature in the first trimester may indicate a lack of progesterone, that is, the probability of miscarriage. In some cases, this is a physiological feature of the female body, so you should not panic ahead of time.
A sharp decrease (or increase) in the basal temperature in the early stages of pregnancy may indicate a stop of fetal development, and uncharacteristically high rates above 37.5 (sometimes 38) degrees warn of the onset of inflammation or ectopic pregnancy.
Low basal temperature in early pregnancy, at which the probability of miscarriage is quite high - this is a condition that can be easily adjusted with modern medications. Also, the diagnosed inflammatory processes can be treated in time. Ambiguously may behave BT when the fetus fades, it can sharply rise or fall, so any changes should alert.
A slight temperature fluctuation in the absence of any alarming symptoms may result from overwork, stress, flight or climate change.
But in any case, with an unstable BT schedule, a pregnant woman should consult a specialist.
Measurement rules
So, we have already found out that by what basal temperature is held by the woman in the early stages of pregnancy, you can determine a lot. However, in order for the schedule to be informative and not to make the expectant mother very worried, it is necessary to carry out the measurements correctly:
- First, it must be done regularly, at the same time;
- secondly, the procedure must be preceded by at least 5-6 hours of continuous sleep;
- thirdly, for these purposes it is better to always use the same thermometer;
- Fourthly, it is necessary to measure BT without getting out of bed.
If all the rules are observed, the basal temperature chart will tell you about the processes occurring in the female body and the nature of the course of the pregnancy.
