8 weeks now, first time mom and 34 yrs old, gas bloating and changes in bowel movement

I was constipated just recently that there was few drops of blood after a very hard stool passed. Although I am not new into being constipated, I observed it happened after taking the prescribed medicines for pregnancy. Then yung milk na nireseta kasi late namin nabili, after taking it watery naman yung stool ko (pero mas gusto ko na ito kaysa conatipated). Hindi ko sure pero yung lang naman yung bago sa intake ko so I checked online prone to constipationand diarrhea daw talaga. Anyone here experienced the same? My next check up will be on the 22 pa. So di ko din alam anong meds itake or anong adjustment sa meds/milk ang gagawin. Right now more on bloating discomfort na narerelieve kapag either nagburp or fart. Tapos mejo parang may slight discomfort na rin sa back/hips. Normal pa rin naman ba itong mga ito? Ang hirap din ng wala kang makatanungan now lalo kapag mahina ang loob gaya ko kaya salamat and stay safe tayong lahat.
