Urgent!!!! Urgently, brother, sister, experienced help me! 20

What you said is not clear enough For example, when did she have her menstruation last time If you know, it is good to judge whether it is a safe period In addition, Yuting ate too late, it is effective to eat within 72 hours Extracorporeal ejaculation is not safe, if menstruation has not come next month, buy a test strip to test it, if you are really pregnant, you have no choice but to go with the fetus Why did you go early However, the chance of pregnancy is still very small, good luck

It is not safe outside the body, and you have to take medicine, but taking medicine after the drug for a long time is not good for your health, if you love her, wear a condom, if you don't love, whatever you want.

You just have to wait to see if her period is on time, and if she is not on time, buy a test strip to check it.

It's not going to be pregnant, I'm afraid that you'll be infertile in the future.

1.Emergency contraception cannot be used twice in a month.

2.If you use the contraceptive pill of the Dingnuo brand first, you can't use other brands of contraceptive pills for three months, hello, let's stop and pay attention in the future

You take two different birth control pills this time, and your menstrual pattern has been disrupted, and your next period will be delayed

Oh, what day is your menstrual cycle, when did you last come, and there should be no problem with taking medicine within 72 hours, but according to the instructions, you should take it, and taking medicine may affect your menstrual cycle.

There is nothing at all, especially outside the body, we have nothing outside the body for a year and a half!

Brother, if you are a man, don't let your woman take medicine!

Bring your own condom! And you can learn about it from the Internet. It's rare to know a little more, and you come up and post a question.

It seems that the medicine is only effective if it is taken within 24 hours.

Will it be;

Indeed, there is a limit to the question of when the reaction is complete, let's say that the concentration of Cu ions is less than 1 micromole per liter, and the hydrogen begins to react.

A chemical reaction cannot be carried out endlessly, and all reactants cannot be converted into products, which means that the degree to which a chemical reaction can be carried out is limited. The reason why the chemical reaction without non-volumetric work at constant temperature and constant pressure can be carried out is because Rg O, with the continuous progress of the reaction, the Rg value is getting larger and larger, when Rg=O, the reaction loses its power, at this time, the concentration of reactants in the system and the concentration of products no longer change with time, and the reaction reaches the state of chemical equilibrium, Rg=O is the thermodynamic sign of chemical equilibrium or the criterion of the degree of reaction.

The key mistake is that copper ions don't matter during electrolysis, electrolyze copper ions first, as for what you said about electrolyzing hydrogen ions, that's not right, copper ions have been electrolyzed into copper molecules, that is, after that, it is equivalent to electrolysis of water molecules.

The later 5 plus the original extra 3, 5 + 3 = 8, the 8 each 2 separate into the cage, 8 2 = 4, that is to say, the cage has 4, then the original pigeon is 6 * 4 + 3 = 27.
