Yes, hormonal fluctuations really do cause us to retain fluids in our bodies. Likewise, sodium intake (increases) can cause fluid retention, as does the body's process of rebuilding muscle when we strength train. Furthermore, our bodies are not machines, they don't release weight on schedule or evenly across time. This is exacerbated in the female body, due to our hormonal fluctuations. In other words, it might be best to average your weight loss over a month, rather than to look at any one week.
I have had weeks where I even showed an increase on the scale, even though I was tracking and knew I should have shown a loss. What happens? The next week or 2 weeks, I show a significant loss. In other words, keep doing the right stuff, and especially around that time of the month, consider it like "money in the bank." You'll see the returns when your body decides to let the weight go.
For this reason, I recommend taking your measurements (waist, hips, thigh, upper arm....). This provides you with another concrete, objective, numerical measure to refer to when the scale is acting ridiculous.
Also, track. Track your food, your water, your activity and your losses. In this way, if you feel like you're getting loosey-goosey with your program, you can look back to weeks or months when you had it together, and duplicate those efforts. And, tracking gives you another good numerical measure. If you're eating in your ranges, know that you're doing good for your body. Your body will, eventually, let go of the weight and build muscle and wellness.
Hang in there.
You can't wait for inspiration. You have to go after it with a club.
