Detox Water while pregnant or TTC?

So back story. My husband and I have been on a detox kick now since new years. If you don't know what detox water is, it's basically naturally flavored water that cleans you out. Whether its with weight loss or just to get the junk out of your system (which is what I usually drink).

My question is, is this safe for me to do while TTC/being pregnant (AF is due Wednesday..fingers crossed!) Anyway the 3 we have in the fridge are as followed..

Cucumber Lemon Mint- Literally just cumber, lemon, mint and water

Weight Loss Detox- Lemon, Lime, Cucumber, Grapefruit, mint and water

Master Detox- Lemon juice, Organic Maple Syrup, Sea salt, Cayenne powder and water

So do you think they are ok to drink? I know your not suppose to do full out detoxes where you just drink water or juice all day for so many days but that's not what I'm doing. I just drink these, usually the cucumber lemon mint one, instead of anything...minus regular water and milk.

Thoughts? Opinions? I tried googling it but to no avail and I don't have a doctor since we recently moved. Thanks ladies! :)
