Possibly pregnant? Opinions appreciated!

Hello, all!

Well this past weekend my boyfriend and I had sex. We always use condoms but I stopped taking birth control several months ago (stupid, I know). We had a quickie so we left all our clothes on. Afterward I was looking at my shorts and there was a fluid on the bottom. He had commented on the fact that there was some "leakage" in my area, which isn't unusual, and could easily be the source of the fluid. We had used a flavored condom so it was difficult to tell the exact source of the fluid. I didn't get a chance to look at the condom after the deed, but he didn't seem worried about it at the time of removal. Now, I use two separate menstruation cycle calendars on my phone, with dates from a few months back, so they are fairly accurate. My next cycle is shown to start within the next couple of days, according to these calendars. They both state that I was "safe" during the time I had sex, so there would be a minimal, but still possible, chance of pregnancy during this time. I was not worried at first, but as the days go by I get more and more worried. He has yet to mention any worries he has about it, but I am such a paranoid person in general, and I am quite frightened of this situation, even though the chances would be slim.

Any input would be wonderful! Just worried, is all. Thanks!
