We are trying to conceive. My complete cycle length varies from 31-33 days. Last menstrual cycle started on 21st September. We tried thrice during the predicted ovulation week, 10th October being the last time. After that, I could see very, very minute redness (almost nill) on the tissue, on and off, when wiped for the next 2 days, along with lower pelvic pain (mostly on my left side). Since yesterday, cycle days 23-24, light bleeding has started, and I am using a panty liner since. Could this be a cause for concern? Would really appreciate if I could a response as soon as possible, so that I can plan for the next steps. Thanks a ton in advance.
