I don't know what is going on with me TTC for a year now and isn't working. I have bled basically all month not consistant but on and off and I went to 2 different dr and they said I have them stumped but yet have only done blood work. This dr gave me an appt for an ultra sound but they said as for the rest they don't know. Please has anyone ever experienced this.   I bled 1-5 medium which is why I thought it was my AF. Had intercourse 6-7 , 17-19 spotting light. Intercourse 21-23. (Spotting 21 aftet inter course but then stopped). Spotting 24-today. But it isn't all day spotting it's like here and there I could go hrours with out spotting then all of a sudden it's there. And the color is a deep redissh brown. I do t know what to do only my right breast is tender and I have bad acid reflux.
