Could i have gone into early menopause

So long story short I got overdosed on contraceptions by the doctors surgery (which I've now left) which landed me in hospital for over a week since the hospital removed both contraceptions ( implant and coil) I haven't had a period at all it's been about 4 months and all I keep getting is hot and cold flushes I've been doing ovulation tests because it got suggested I should do that see if I'm ovulating at all so i have been doing them for the past 6weeks and I haven't been ovulating at all I've done sevral pregnancy tests just to be sure that I'm not pregnant and they all said negative ,ive got a doctors appoiment comming up which I will ask them if they can see if I've been made infertile or not but I was just wondering if it is possible that my previous doctors has caused me to go into early menopause? As I am not one to Miss a period at all never have done no matter what contraception I've been on Ive always come on on time even when I haven't been on anything they have always been regular.
