I'm currently almost 18 weeks. This is my 3rd baby. Over the last couple weeks I had a few moments that I was sure was baby. Now, it's been a good few days at least since ive felt anything concrete... I kinda expected it to get more often once I was able to really pin point it was baby... Is it normal to feel it at this point then nothing for a stretch of time? I know a lot of women don't feel anything early, but I'm pretty familiar with the sensations at this point. Really trying not to get anxious about it.
