I went on nexplanon Dec 1st and I was supposed to get my period the 7th and never got it so I figured I just wasn't gonna get it for awhile while on the birth control since that's what I've read is common, however on the 23rd I had old brown blood when I wiped and then on the 26th I had a little blood only when I wiped though like not enough for a tampon or anything a few days after that I got full blown blood and now I've had my period for 10 days and I'm just starting to get cramps now and they're pretty bad. I feel like this is never going to end!
