Worried about cervical cancer

so I have a smear next week as I have been experiencing pain during and after sex. I’m 26 and I have a 20month old. I suffered terrible pelvic pain during pregnancy and that hasnt really gone away. It’s definitely eased but hasn’t gone. I am extremely fatigued all of the time and I ache everywhere. I don’t bleed in between periods albeit they are not regular. My vaginal discharge also smells extremely strongly. Finally I suffer from blood blisters only in my groin area. Should I be worried about these symptoms? Any tips? Thanks.
