Hello, Thanks for writing to us. In this case, I suggest you to undergo one home pregnancy test or blood test for beta-hCG to rule out possible pregnancy. Additionally, one TVS scan will be helpful to determine miscarriage or viable conception. Other reasons are hormonal imbalance, old endometrial tissue, vaginal/ pelvic infection, mental stress, obesity etc. One routine urine examination is also advisable. Following initial test result, you need to consult with gynecologist to proceed other investigation and take suggestive measures accordingly. Till then, maintain genital hygiene, avoid stress, drink more water etc. Good luck.
