I had roamed in heat 4 to 5 hours and after that there was pain in my vagina. On the very next day there was mucus tinged with light brownish color and next there was light brown discharge that is on 16th days.. and I am feeling fatigue since that day along with mild bodyache but no fever. I don't know why this has happened. We are trying to conceive even. Please guide me here. I don't have any problems like endometriosis, fibroid or cyst. Yet this is happening. Can it be due to ovulation or anything else ?
