Hi(: I Am Not Sexually Active And A Couple Weeks

Hi(: I am not sexually active and a couple weeks ago my boyfriend fingered me and afterward we noticed a lot of blood on the seat. This has happened a couple times before and I brushed it aside, but this time there was a lot more blood and it kind of freaked me out. It's been 2 weeks since this happened and I'm still having light bleeding. I have a history of irregular periods and initially thought it was just a case of getting my period at an inconvenient time, but the more I think about it the more I feel like these instances aren't just coincidental. I'm having trouble finding a gynecologist in my area that takes my insurance and I don't want to pay a lot of money to see someone if it's not something I should be overly concerned about.
