Hi, I had sex with my husband on the day of my ovulation(14th march) till one week after, I had brownish spotting on cycle day 1, normal bleeding on day 2, spot on day 3 and 4 and end it with mucous mixed with brownish string. Have been having heartburn and indigestion, fatigue sometimes headache. My boobs were sore, bloated tummy, feeling pregnant but the result came out negative, I have tested 4times. Today is the 10th day of my menstrual cycle. What could be the problem.
