Hope I didnt' pull a muscle??

Today was my 3rd day stretching for the 3 splits (doing half hour each night, holding each position for almost 2 mins). So everything was going great, in only 3 days I saw considerable improvement, especially for the middle splits which surprised me. Then suddenly in my middle splits stretch (maybe a foot off the ground) i felt something pull or kinda re-adjust in my left hamstring, so i stopped. It didn't hurt, just felt awkward, so I got scared and stopped my stretching. But if it was a pulled muscle I would know right? It would hurt right? Ahh I'm gonna wait til tomorrow to see what happens... if I don't feel anything I guess I'll do my stretch routine, but take it a bit slower. (ps- i had warmed up too). I'm so afraid of pulled muscles uuughh!! 😠
