NuvaRing question

Va

Hi everyone, it’s my first time using this to ask questions hopefully some of you can help me out with what you know. I’m currently using the NuvaRing I been on it for about 5 months now. I’ve gone through the whole spotting and stuff but haven’t gotten my period because I been using it for 4 weeks due to the fact that I been traveling a lot. Anyway it’s been about three weeks since I been feeling dizzy and nauseous. I experienced the side effects during the first three weeks and then they were gone so idk why I feel like this now. I also feel really tired and sleepy most of the time idk why this is all happening. Idk if I should worry about pregnancy yet since I been using the ring their whole time?

Well thank you for your time 😊
