My last menstral cycle was April 10. I have a 30 day cycle that normally lasts 5-7 days, and always have what looks like blobs of dark colored blood come out especially on the first day. I had intercourse with my husband several times for the 1st time in over 5 years. Not long after tgat I was having what felt like p.m.s. cramps off and on every day. My cycle was due on May 10, but all I got were soar breasts instead. Finally 3 days late I began to bleed, but it was not like a normal cycle. There were no clots at all and the blood came out as if it was mostly water. This only lasted a day and a half, then I only had spotting for like 3 days after that. The day the blood came my brest stopped being soar. Could this be caused be stress, should I see a doctor?
