15 weeks + 1 and have some anxiety

Hello ladies, I was hoping someone may of had the same experience and could potentially put my mind at ease and let me know what they think I should do… This is my second pregnancy and I started showing at 8 weeks. By week 10 I thought I could of felt some movement as it deffo felt like it but I put it down to gas and moved on, by week 12 I could definitely tell this was movement and I’ve been feeling movement for sure from week 12. It’s been nearly every day once or twice a day but this past week it’s gone very quiet. I feel like I may be over thinking and perhaps baby has now moved to a place where I wouldn’t feel it as easy but I also feel like if I explain it to my midwife or doctor they are going to call me crazy and put it down to me feeling gas all this time. Any advice is greatly appreciated and thank you for taking the time to read x
