My period is always either 23 or 24 days apart..lucky me. But my last cycle was only 21 days..I'm not on bc so I use a website and app to track my period and see when it suggests ovulation..both said I should be ovulating between march 2nd and 7th and I had sex on march 5th. We aren't trying yet so he doesn't purposely go ...inside. I was due for my period on Monday the 21st and haven't gotten it yet or really had any period symptoms. What's strange not that I think about it is about a week or so ago I had horrible stomach pains that kept me up all night but I thought I ate something bad..but never had a bm and it was gone the next morning. I think I feel nauseas but that may just be nervousness...have I mentioned that out wedding is in 2 1/2 weeks? I took 2 pregnancy test, one last night and one this afternoon and both were negative. Do you think it's the cheap test or time of day messing with it or should I definitely be showing up as positive now?
