Calling all doctors,nurses,or mommas

Recently I’ve been dealing with something and I’m not sure what it is. To give a little background I’ve been dealing with a major headache, on and of nausea, chills and cold/hot sweats, and major back pain. The last time I had sex was unprotected on April 29. I’m currently on birth control and we used the pull-out method. So it’s been a couple weeks and I’ve felt fine but not I do have some itching and discomfort down there. There is no discharge and some dryness. ( should also mention I got a new toy and maybe allergic to the cleaner? I used it a couple days ago and that’s when the itching kinda started, the burning sensation isn’t present tho,only a lil towards my bum) <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says I’m 3 days late but with my birth control it’s been odd timing for when I actually get my period. I’ve been dealing with a lot of stress as well. Moving cities, finals,etc. I am now on vacation for a short period and have been feeling the worst. It started Sunday. This was a 5 hr car ride and I’m easily car sick so that amped everything up. I’m not really sure what I’m dealing with here, an General sickness, being overworked and my body has had enough,STI, STD, or REALLY horrible form of morning sickness but any advice helps. If this doesn’t subside I will go to the clinic on Thursday but money is tight so if the thought is that this could blow over that’d be soo much better. Thanks girls ❤️😊also please be kind, I’m just curious and questioning a couple things and need a little help.
