Constipation or something else?

Hi ladies, so I’ve been having some strange stomach issues lately. I was sick with what I believe was a sinus infection but before I was on 875mg amoxicillin, I previously took Mucinex liquid DM and the Night Shift and I noticed that I was constipated slightly so I took a Dulcolax softchew (youre supposed to take 2-4, but i didnt want to be on the toilet all day while at the office 😅) and ended up going that day, but the day after i went back to being plugged up, my stool is a light brown yellow color. It’s been going on for around a week and a half and now I have reduced stomach sounds and I feel like I need to go, but when I do, it is not as much as I think it’s going to be. My stool goes from being smooth soft thinner piece to more formed smaller piece. Im getting worried to might potentially be something else. I can still pass gas every now and then, so i dont think its a bowel blockage. If anyone has any comments, id love to know, thank you!

Update: i was back to normal for about a week after i was sick and one day i woke up and could really go to the bathroom, ive started taking a probiotic recently so hopefully that helps things, but my stools are still very soft and small, i go 4-5 times a day with not that much of a result. I think im going to go to the doctor at some point to make sure nothing serious is going on. This has only started happening this month and it was sudden. I went in for a kidney stone around this time last year and during the CT, they didnt find anything unusual other than the kidney stone. So im hoping nothing cropped up over this year.
