Etonogestrel
"I am 20 and have always had anxiety about BC and not trusting that it is working (I could always use it exactly like I'm supposed to and would still make myself sick over if I was pregnant or not) this has definitely lessened that feeling!! If your like me I always Google my symptoms to see if anyone else is feeling it too so let me tell you.. I've had it for about 3 months now, and things are a little rough. I've been bleeding almost everyday since I got it.. Except for those first few weeks. But it's only minor spotting. My first period was just like normal (only 4-5 days too) and my second and third has been a little wonky. (Not on time) but I'm holding out that it'll get better! I wish you all luck!!!"
