I May Have Caught An Std Pls Help Me

heres the deal: i have been having sex with a girl for about 2months now. we have unprotected vaginal, anal and oral sex often. we typically have sex 3-5 times per day, 6 days a week. recently, some parts of her past have came up and its very frightening.

i learned she has had almost 30 sex partners and have seen her diary which read of her catching crabs about 3 years ago. since ive been with her, she contracted a yeast infection as well. sadly, considering her past, i have reason to believe she may have more diseases of which i am not aware.

since i have learned all this, i fear i may have caught something. I have no pain, blisters, bumps or anything abnormal on any area of my gentitals. no discharge, burning, nor tingling, nothing abormal at all, and no symptoms of anything. but i do have an odd, almost soft pain in the area below my belly button and it feels like its behind my stomach, meaning its internal, nothing topical. and its nothing related to having to go to the bathroom, its more like a sore muscle feel.

i have also been feeling a bit fatigued recently. but i accredit this to the fact that i have learned of all this in the past 24 hours.

i am very nervous that i may have been exposed to something and was tested clean of everything at my last test immediatley before meeting her. she told me she was tested clean this past june, but again i am positiive she has had at least 2 sex partners between then and myself.

im not sure if i have a legitamate infection of anything or if my body is just reacting to both the immense volume of rough sex im having paired with discovering these horrible secrets.

i hope i gave enough information, i can give more details of any aspect, but i feel its well explained.
