I had Nexplanon put in last July 3, after starting my period late on July 2. The doctor was VERY knowledgable and actually had it herself. She said about a third of women have no period, a third of women have regular periods, and a third have unpredictable/long/bad periods on it. She also told me that when you get it put in often has a big impact on that (so it is good your doc is putting it in the first day of your period), and if I did start getting crazy periods to call her and they could try some mess to help get it regulated.
i have had NO periods since I got it (I was very regular previously, both when on nothing or on the pill). About two weeks ago, my boobs got SOOOOO sore. Like even just my arms brushing against then was agony. After about 5 days of that, I finally did get a mini period and the pain went away. It was the shortest, lightest period I have ever had.
I did have a massive bruise from insertion, and it sort of itched/was a little uncomfortable for the first month while it healed. It didn’t hurt, I sort of just could feel it sometimes. I think it was scar tissue forming.
I am VERY happy with it. I am surprised it isn’t pushed more, it seems like not a lot of women know about it. States are that it is more effective than sterilization (!!!), and I like that it doesn’t have the risks an IUD does. It just seemed scary to me to implant something inside where it can travel or perforate. My understanding is Nexplanon actually uses LESS hormones than the pill and is safer even as you get older.
I will say, for someone who was regular, having no period is an adjustment. I have freaked out a few times thinking, “OMG what if I’m pregnant? I don’t want to end up on I Didn’t Know I was Pregnant.” I am plus size and could probably be pregnant for a few months without noticing. So I bought a pack of 25 test strips for $8 on Amazon and test anytime I feel like it. My period used to be my monthly test, LOL. Also, I do use an app on my phone – I used to use it to track periods, but now I use it to track when Darling Husband and I are intimate. May seem excessive, but if I were to get pregnant, I sort of want to be able to look back and see when.
I had to pay $425 out of pocket for it (my pills were about $25/mo, so my break even is around a year and a half), and it was totally worth it to me! I was part of that big birth control recall a year ago February – my pills were part of the recalled lots where they had put in sugar pills instead, and I had already taken them so there was no way to check if mine were bad or not. I LOST my mind. That’s when I started investigating other methods. Very glad I did. Hope this helps.
