I have my first and last period on March 31, 2019 and during my ovulation week we did have sex a lot, but I did have very light pink spotty during my ovulation then went away and now my breast feel sore and nipple is sore also I do have a very low cramp pain, I supposed to get my period in few days, I never get my hopes up being pregnant because always is false alarm for me, but I need any suggestions or advice, what could be? Early pregnancy sign or sign of my period coming? I always want be a mother but I never have chance.
