Mid-cycle spotting is not uncommon due to a normal drop in hormone levels. Your symptoms may be due to hormonal imbalance, if the symptoms persist for more than one cycle, it would be prudent to see consult a gynecologist. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex .
