This is a big change for you.
You are allowed to decide what happens next.
That is a big responsibility.
But there are lots of people who can help you.
It is important that you take care of yourself.
That includes your health.
You should visit a gynaecologist.
They will examine you.
They will also give you tips on staying healthy.
For other questions there is a pregnancy advice centre.
The people there will help to answer your questions.
You can find one on this website:
http://www.zanzu.de/en/themes/being-pregnant
http://www.familienplanung.de/beratung/beratungsstellensuche/
You may need someone to help you search.
The website is currently only in German.
Maybe you can go there with an interpreter.
