Last night, my boyfriend and I wanted to have sex with each other. Unfortunately, my cycle came on before we gotten anything aroused all the way. Instead, we cuddled until it was time for him to go to work. A few hours later, I spent some time in the bed and I had an urge of embarrassing flatuence. The last time of that made me got up in an instant. So I went to the bathroom and checked my sanitary napkin and there was a plum sized blood clot. I felt a little weak I was scared to say anything about and I took a shower so I can go to work. I thought that I might have another episode so I took plenty of sanitary napkins . Every so often, I would go to the ladies restroom and check to see if I am bleeding at all, because I stopped bleeding after the shower. Now that it is close to bedtime, I am still not bleeding!!! So please tell me what is really going on. Is it because of stress?
