I had sex and he came in me on the 16th which according to the app it was my second to last ovulation date. I’m currently 3 days late on my period according to the app and my period is regular. I took four test two were unclear and two were negative. Could I still be pregnant? Or is my period just being weird this month? I’m also not feeling my usual pre period pains like sore breast I’ve only gotten some cramps. What do you guys think?
