Movement? 15w5d ftm

Rachel

The last few days I've been feeling this rolling sensation between my hip bones. Its different than the occasional boops I got a couple of weeks ago too. I know they say first time moms feel movement later in the pregnancy but I'm positive ita not gas, lol I can tell when its gas. But also the last 2 days along with the rolling sensation I have been getting some quick, sharp, pains in the area the rolling happens. I've had no spotting and this is a rather new development for me. I'm just not sure if fetal movement cause subtle pain like I've been getting. Any advice?
