What causes inconsistencies in menstruation?
Patient: Hi, I ve been trying to conceive. I had intercourse 3 days before ovulation (day 14) and again during ovulation (day 17). My period was 4 days late and when it did show up the first 2 days were very light and bright colored, my period stopped completely on the 3rd day and was back again on the 4th day but lighter and shorter than the previous days. I have also been feeling nauseous and have now noticed a weird rash on both sides of my neck. I have had 4 home test that were all negative. I am just wondering if, based on the symptoms above, I have conceived. Doctor: chances are less that you are pregnant because your tests are negative and you had bleeding almost on due date. still wait for 1 week and do repeat test.  rash could be because of some other reason.
