Your English is fine. We have native English speakers who don't write as well as you do. What the ladies are not used to is writing on here as if you are texting. Texting is hard to read...
I don't know why some people jumped to the conclusion that you might be trying to get pregnant without telling your partner - that leap from what you said makes no sense to me. When a couple is excited about trying to get pregnant, it's common to get anxious and nervous. We get LOTS of "Could I be pregnant" questions here on this board, and yours won't be the last.
One of the best things you can do to help yourself get pregnant is to RELAX. If you have always used condoms, you will have to get used to the difference. It's kind of like you "leak" a bit for a while. If you weren't trying to get pregnant, you'd be running to the toilet right after intercourse so that most of it will come out right away. (It's also good to urinate right after sex to help prevent UTI's.) But to help you get pregnant, doctors say to stick a pillow under your butt and wait for a while before going to the bathroom.
Are you taking pregnancy vitamins yet? If you aren't, go get some today. Tell the pharmacist that you are trying to conceive and ask for a recommendation. Pregnancy vitamins are supposed to have folic acid, which will help prevent neural tube defects like spina bifida. Also, it will help prevent some forms of cleft palate. This is SO important in the first 8 WEEKS - the 8 week mark is where the palate actually CLOSES. The reason to take pregnancy vitamins before you get pregnant is because you could actually be 8 weeks pregnant before you even know it, and then you'd miss getting the benefit of those vitamins for everything you need them for.
Some people get very upset when they don't get pregnant right away. It doesn't help. Looking at it like a process is much better.
