I had sex April 9th, he definitely came in me. No doubt. I bled that month. In May, my period was over a week late and very short. Also very light. Now today, I'm 4 days later than what it was last month with no signs. Just a bunch of nausea and headaches. What does this sound like to you all? My periods are usually very regular. Nothing has changed for me. Still working the same and eating, sleeping the same. I've not been stressing over it or really even thinking about it and I wasn't "trying" per say so I've not been really hopeful either. I know those things can make you irregular. I did take a test but it was about a month and a half ago and it was negative. I started Googling last night and read that many women bleed as if they're on their period in the first trimester and that it can take 3-4 weeks passed missed period for a positive test sometimes. Just wondering what you all think?
