Me and my Gf had sex 6 days before. well it was not a complete sex act. I just insterted mine on her for like couple of seconds. we didint used condom since i was sure i know when i came. But after first time doing that i pulled it out before cum. I cumed in my shorts. But Later after some time i inserted it again (wihtout cleaning it, hoping all cum has dried out). Few movements for a few seconds and i stopped before i feel cum. 

It was almost near her ovulation period. Calculated and know almost two days left for her ovulation. Also i heard sperms wont die soon. After all that, hoping i dint came inside her, i was standing but i saw my pre cum comes out me without knowing, follwed sperm( but before that mine was looking dry) At that point we got scared

Its been 6 days. She feeling so tired, cramping in stomach, feelings like noisea, she had headache for 2 days after sex n not now, and minimal urinating(she dont feel to urinate but feels dehydrated) no other symptoms as i asw in internet. plz help. we are so worried. 

I think i dint came inside her, but what if it go without my knowledge.
