Colace users!

I’m 11wks 3days along with my little babe! My constipation has been horrible. I’ve tried tons of water, apple juice, probiotic yogurts daily, prune juice which made me instantly throw up lol I’m so so uncomfortable. I got a mess safety list from my doctors office that was mailed to me around week 6. At the top of the list it says to avoid all medications until around week 16 if at all possible which is what I’ve been trying to do but I’m at my breaking point. I’m about to take Colace the regular strength one since it’s on the safe list, the dose says 1-3 pills to take as a whole or divided throughout the day, my question is.. is it okay to just take two pills in the morning and see if that helps anything or should I divide it up into three times a day. I’m anxious about taking any meds while pregnant and if I could avoid it all together I would.
