Should i worry?

Title is click bait but i didn’t know what else to say🤣 basically i’m 16+1 today and i haven’t really been feeling “pregnant” i know it’s normal but i still worry, the last atime i saw bub was at 9w6d and i don’t get to see him/her again till 18-19w anywho since all my first trimester symptoms are gone and all i have is constipation, back aches, some boob aches (not as bad as it was earlier in my pregnancy) and sometimes acid reflux i’m wondering if any other mamas are going thru this or have? i’m also a FTM, thanks ladies🤍🤍
