My cycles have always been 28 days long. My stimated ovulation day was the 15th of my cycle . I have had unprotected sex the 9th, 17th, 19th of my cycle ( that are supposed to be not fertile days) and my period is late. Today is the 31th of my cycle. I have taken a couple of tests but they are white . I feel crampy, my temperature has slightly increased ( it has been low the previous days). I think that my chances of being pregnant are very low . What do you think? I'm quite worried because I have a 14months old baby and I feel It would be too soon to be pregnant because he still needs a lot of attention. The first time I got pregnant the tests took some time to show positive.
