Brown blood, 5 weeks 6 days ☹️

Er

Has anyone else experienced this? I’m trying not to freak out. My husband and I had sex for the first time in 2 weeks last night. Could it be related to that? I just went to the bathroom and there was brown discharge or blood in my underwear. Not a lot of it. But just two small spots of it. A little more came out when I peed.
