My period was supposed to come on Friday the 16th, but it never did. I tested on the 17th and a few days later with dollar store HPT, both were negative. The second one had a faint line on it, but I am pretty sure it was an evaporation line. I have been really bloated ever since just before my period, sore breasts, especially right now. The bloating has gone down but I have also been extremely hungry lately, and been getting headaches. Last night suddenly around 8 PM, I thought my period had started because I went to the bathroom and when I wiped there was blood on the tissue; however it was extremely minuscule. Later that night I had intercourse because the flow was not heavy or even noticeable. It was unprotected, but he used the pull out method. (I know not a real acurate method). Afterward, when I went to the bathroom and wiped it was the same very very light pink blood on the tissue. I slept with a pad on thinking my period would start, but this morning when I woke up there was still nothing on it, and there was a more brownish pink blood when i wiped, but just a tiny dot. What could this be????
