I am on day 38 of my menstrual cycle. I normally go between 26-28 days on my cycles. I have taken 2 pregnancy test with a negative result. I have NEVER missed a period without being pregnant ( 2 pregnancies). I have been taking Lexapro for the past year. I have stopped cold turkey due to was not sure if I was pregnant. My concern is not having a period with a negative result on a pregnancy test. I have been feeling dizzy, small cramps, tired, and moody. I am so confused. Anyone have any input?
