Nuvaring could of made me pregnant..??

Ok... where do I start?!

So beginngin of March I decided to get on birth control. I resulted in the NuvaRing. After my period I put it in. After only 4 days of being in I took it out. I immediately was having the worst side affects from it. Well little did I know that you have to wait at least two weeks to a month to have unprotected sex. So the minute I inserted it I thought I was good to go to have sex. I ovulated the day I took it out and we also had sex that same day... after I took it out a couple days later I bled for one day. Than the week after I bled again for like a day. Than again a week later and than again another week later. So for a whole month I bled every week. I haven’t bled for about 3 weeks now but after my last “period” I guess you could call it I started feeling so sick, tired, boobs hurting, headache. Etc.. you get what I’m saying?! All pregnancy symptoms.. so last week I finally took a pregnancy test and it showed up positive. So I took another one the next day and it was negative 🤷🏽‍♀️ the sickness was getting worse so today I took another one and it was negative again.. 😒 were not trying to to have another baby but I’m sick of all the symptoms and no answer!! Could it just be side affects still from the birth control and screwing up my cycle so bad?? Answers please!!
