hello, i am a 22 year old female. my boyfriend and i have been trying to conceive for 6 months now with no luck. my period came right on schedule on August 25th and lasted for 6 days. afterwords i used an ovulation predictor kit and got positive results on the 9th 10th and 11th of September. my period was then due on September 23rd. It was late. Then on the 27th i had a small amount of light (very very light) pink on my toilet paper when i wiped after urinating. then it went away for 2 days and on the 29th of Sept. through the 1st of Oct. i had brown spotting, only enough that i needed panty liner. then yesterday (2nd Oct.) there was absolutely nothing going on down there. When i woke up this morning i am again having the watery light pink spotting. only noticeable when i wipe after urinating... My periods are usually right on schedule, very heavy and are accompanied by painful cramping. I have been having off and on light cramping and back pain . so light that its barely noticeable. i took a home pregnancy test on the 24th of Sept. and it came up neg. i haven t tested since. I do not know whether to count this as a light period or if it could be signs of pregnancy.
