Pregnant- Advice please on tissue salts :-)

I am 7 months pregnant and have recently found out about tissue salts. I was researching what I can take during pregnancy and found out about a Pregnancy Program of tissue salts created by homeopath ‘John Damonte’. Since I am 7 months, it says to take CALC FLUOR, Mag phos, Nat mur. I am unclear on the dosing because every where i search online, different instructions are given. Some websites say to take one dose of each once daily (all together I assume). According to my bottles 4 pellets are a dose. So that would be all 12 pellets at once. But some sites say to take 1 pellet of each twice daily. Some websites say 2 pellets of each twice daily. So which is it?
I am also interested in the method which allows you to put 1 pellet (of each Calc fluor, Mag phos, Nat mur) in 8 ounces of water and shake, then sip throughout the day. But how many sips- do you space them out every 2 hours or what? The directions I have come across are not real concise.
P.S. I will note that at this current point in the pregnancy my biggest complaints are : sore/achey in inner thighs up in pelvic area-feels like the joints/ligaments that connect my thighs to my pelvis are sore, sometimes makes it difficult to walk or move around; sometimes round ligament pain; sometimes sharp pain around the area of my lower inguinal hernia repair; pain in the pubic bone at night when turning from side to side; don't know if there are any vaginal varicosities, but the area sometimes feels swollen. I started wearing a baby belly band with compression therapy groin bands to help support my pelvis and thereby help with all these issues.
Any advice appreciated!
