I have been nauseous for the passed month now, have been extremely sleepy and started lactating around the same time the nausea started. I ve taken two tests and both were negative. I also started my period on time. My cycles are very regular anfd my flow is always the same. This passed cycle was very strange though. It was normal when it started then it stopped. It started back up the next day and stayed normal for about 24 hrs. It stopped again and didnt start back up until i had intercourse with my fiance but it only lightly flowed for about 2hrs. Any suggestions?
