weight gain?!

Sa
Hello ladies, anyone around 10-12 weeks having a little weight gain ? I've just gained around 2kg in a few days!! I've gone holy sh*t!! So stopped eating junk! And thought about what I'm putting in my body and lost 1/2kg but is this normal to start gaining now? I'm not too sure?!? 😳💖🙊🙈😊👍🏼
