I'm not trying for a baby, I had sex twice lol. I just freak out over little things.
I felt like that for awhile after. Your homones are going crazy and attempting to resettle. I'm confused if you're trying for a baby (you seem like you are, but say you don't) so you could very well be making yourself think you are. You need to be using some form of protection or birth control if you're not. You can also see a doctor for a blood test and it will tell you an accurate answer.
Yeah I plan on it, it was only one time.
You could ask your doctor for a blood test which would be more accurate. Sometimes though we women can trick our bodies into believing were pregnant even if were not. However if you are trying to avoid pregnancy I wouldn't have unprotected sex.
