Dont know if i should worry=////

Im so not typically a worried type when it comes to pregnancy this is my 5th time. But iam starting to become concerned.. i had already felt little flutters and very soft kicks starting at 13ish weeks.. and then randomly soft kicks as times gone on.. but its been nearly a week now i haven't felt anything since .. im now 16 wk 5days i always always felt my kids earlier than normal
