Am I in danger of demoting?

Ok so a day ago i made it to Silver 5 after grinding for the season. I Know there are two months left before the season ends so I am tempted to try and see how far i can climb within that time span. Now today i just won my first match in silver (woohoo) but i also lost a game. Now im currently sitting at 10 lp with silver 3 mmr. If i lose my next match will i demote? Im asking because granted this is my first season i do want to keep my silver rating, but admittedly going all the way does seem exciting to me. Answers please?
