After a miscarriage, is it pregnancy in the following situation?

Patient's question:

December 25th had sex
January 20th had sex again
February 2nd had sex but didn’t withdraw inside, but the hand with dry semen touched the lower part
February 10th inserted the penis but didn’t withdraw, then withdrew outside and touched a bit before ejaculation
February 15th felt extremely dry mouth lately—is it possible to be pregnant?
If pregnant, will the child be healthy?

Doctor's answer:

You are currently considering the danger period, and it cannot be completely ruled out that you might be pregnant. Even if you are pregnant, there are currently no symptoms. If you feel dry mouth and tongue, it may be related to drinking less water or the indoor air being too dry. If you are pregnant and prepare to take a normal check, it is possible to take folic acid orally in the early stages of pregnancy to prevent fetal cardiovascular malformations. It is beneficial to eat more fresh vegetables and water for a healthy baby. If your period is delayed by one week, you can not test your urine early to see if you are pregnant.
