TMI but desperate!

Ladies, this is tmi but my vagina BURNS & has a very intense itch All the time!! During sex, after sex, just sitting, changing positions when I'm laying down. I've tried everything. I got oral medication, got monistat (the 7 day one), different itching creams, even coconut oil!! I'm 15 weeks pregnant and don't see my doctor for another 3 weeks. It keeps me awake most of the night and can start hurting so bad I start to cry. I'm getting stressed out!! My boyfriend checked for me and said that I am very dry and peeling but maybe that's just from me itching lol please help if you've been in this situation
