How long do symptoms last?

Megan
I got the birth control implant out 3-4 weeks ago. How much longer should I expect to have hormonal fluctuations? My doctor said it would be out of my system within a couple days, but tonight my husband went to the store to get more grape juice because I thought I would just die if I didn't get some. About a week after I got it out I had a really short but heavy period (2 days), and then I spotted one gush a week later, if that tells you anything. I've been trying to track my temps, but they're pretty consistent, with a few outliers. Any thoughts? Thanks!
