I'm waiting until the 29th to take a second test. My last period was the 21st of October. I had sex the 28th, 29th, and 31st. Which were days I was able to get pregnant. I started spotting the 17th-22nd of this month, which I was supposed to get my period. It looked exactly how spotting was supposed to look. I only saw it when I whipped.
