help??

Okay so, 
I just moved in with my long distance boyfriend about a week ago (!!!!!!!!!!) and we've had a lot of sex since then. 
On thursday night, we went fishing, and I got bit by mosquitoes. A lot. I have bites on my butt and inner thighs (as well as the rest of my body too) even though I was wearing long jeans. 
Friday morning, I woke up and had to pee. Nothing unusual until after. After I finished peeing, I had a sharp stinging pain downstairs. I have to pee really often, and when I do, it still hurts. Last night, I went to the bathroom 3 times and every time, when I wiped, there was a tinge of blood. This morning when I woke up, there has been no blood and the urge to go pee has diminished slightly. It still burns afterwards though. 
Since the pain started, I haven't had sex, and my symptoms have started to go away. 
I have recently been std tested and came up clean, and I'm also his first and only sexual partner, so the risk of it being some sort of infection or disease it out. 
I've had a UTI before, and it felt somewhat like this, but still really different. 
Do you think it could be a UTI, a mosquito bite, or just too much sex? And if so, what should I do? 
Going to the doctor isn't an option until November 1st, so maybe some homeopathic remedies?
