Baby Movemements

I am expecting my second baby and I am 14 weeks, with my first little one I felt her kicks clearly at 13 weeks and felt her move from then on, but with this baby I felt her flutters last week at 13 weeks as well and nothing since. It makes me nervous because my placenta is anterior and I should be able to feel flutters sooner, I know that generally you start feeling them by 20 weeks at least but I know my body. Just wondering if anyone has experienced something similar.

Edit: I got it mixed up, I actually have posterior placenta, so feeling baby should be a bit easier.
