I'm in the middle of taking Semaine and I see a BIG difference in how I feel. Last month I was tortured by cramps and this month is SO much better!
Kaitlyn, Atlanta GA
I've had a few cramps here and there, but overall Semaine has been a miracle
Lauren, Salem MO
I always want to take ibuprofen or Aleve but know they will never help, so I never do – but Semaine did!
Diane, NYC
I had energy all day – felt refreshed compared to feeling sluggish and irritable all day. Plus my cycle was shorter!
Christina, Atlanta GA
The thing I've noticed most is my energy level. I've had so much energy for all my work and was literally dancing in my office!

2 months in and love it!

So far so good! I have been using Semaine for two months now and my periods have become shorter in length and my flow has become lighter. I have also been able to use A LOT less pain medication. My cramps have not completed gone away but I am hoping to see them decrease even more as I continue to use Semaine. I have not see any improvement in my bloating yet but I will continue to monitor this.

Epic and totally unexpected

I have to admit I was extremely skeptical as I have battled with painful periods, horrible excessively bleeding and cramps that were crippling. I had been on BC for 10 years and finally decided enough was enough as the BC had my hormones all out of whack. Even though I had no periods (eventually from being on BC so long) and no cramps; I had major and random mode swings, BV and UTI infections if someone was to breathe on me. I was bloated all the time, bad acne and just over all tired on the imbalance. So I stumbled over the is product on insta (I believe) and began hiring off emails to get the tea. I knew I was taking out my BC soon and I wanted to be prepared as much as possible for what was to come. I have been off BC since Oct 2020 and my cycles are regular with 28 day cycle with periods lasting for at least 4 days. This product has done so much that I cant believe that is worked, however it could be that my body is responding better now that I am in my 30's and not my 20's. My periods are way more manageable and I do not have to miss work, school or be put in the hospital due to the cringing pain of cramps. I haven't tried the sex thing just yet as I am abstaining from sex, so I am not sure how the sex is, but I believe if all the other issues are this mild then I should be fine. I am waiting until Dece 2020 (which is my 3 month mark) to really evaluate the progress of my period with the product. I am even going in to speak with my doctor about having a baby soon.…

Didn't work for me :(

I had high hopes for these supplements because of all the positive reviews from women who have suffered from menstrual pain. My plan was to start taking the capsules a day or 2 before I expected my period to start, but it ended up coming 4 days before I expected it to. This has been happening every month for a while now. It comes earlier, so it's very hard to track. I'd taken 2 capsules Sunday morning, but my period started a few hours later. Then came the cramps and gas/constipation. I continued to take the capsules as instructed, but I still had to rely on ibuprofen and hot green tea for the pain. So I'm not sure if it's worth it to keep the subscription. I would like to try again next month, but as of now, I am hurt that these didn't do anything for my pain.

Semaine Health

Hi Terri,

We are so sorry to hear that you didn't feel better after your first time using Semaine. Most of our users do feel the benefit after their first period, but our bodies are all different and respond in unique ways. Even if you didn't have any reduction in pain, the ingredients in Semaine are still helping support your body through your period by reducing inflammation.

We've had several users who have noticed a dramatic difference after 2-4 cycles. We know it's difficult to track your period, so we would recommend starting 2 pills a day 4 days before your period might start, and then increasing the dosage to twice to three times a day once your period starts. That way, you are getting on top of the inflammation (at least in a smaller dose) before your symptoms kick in.

We know from personal experience how hard it is to have your hopes up when looking for pain relief. We are rooting for you, and hope that this next month will be so much easier.

x Lauren
