Am I Pregant or just Paranoid?

[yazkin1998]

Hello ladies, I’m new here so it’s nice to meet you all!
Well, let me begin:
I had sex with my boyfriend on 2nd of May which is Day 5 of my cycle (and the last day of my period). We did use a condom but he initially put it inside out so he might have gotten precum on it as he does tend to get loads but we completely neglected that. Now I know how low the chances are considering I ovulated on 14th May which is 12 days after I had sex and the sperm would have pretty much died off by then but I don’t want to rule anything out. A week after ovulation, I started getting some gas issues accompanied by mild nausea and bloating. I did have abdominal cramping but they subsided once I used the bathroom so perhaps that was the cause. Last night, I noticed some brown-yellow discharge (more like less than a teaspoon) and while it isn’t something very new to me but I have never previously paid attention to it. My breasts are not sore and my energy levels are normal. My period is due in 4 days but I can’t help but wonder if this is PMS or early signs of pregnancy. What do you think? Is it possible for sperm to survive that long enough in my body from precum to impregnate me or is it just stress/PMS?
