question: 27 healthy. Vit d deficient; taking supplements. Vyvanse 40mg prescribed for adhd. I am on oral bc and have been consistent give or take an hour/two here and there. I do not know my last ovulation. My last period was around Jan 27th. February my breasts became tender as normal and then I thought I had my period. I only bled for 3 days and it was so light that I could have gone without even my liner. Another thing I would like to point out is that typically no matter how light or heavy my period is my breast tenderness seems to go away almost immediately as soon I start bleeding. My bleeding, as mentioned, has stopped. I still have tender breasts. My period was due to start a few days ago, however, my days do seem to lag a little later and later and with February s short month I don t doubt that my period could possibly be due to start later- I tested negative- my pathetic period came and went a few days before my real period was due to start, and took none of my breast tenderness/swelling away. I ve also been experiencing minor cramps leading me to believe my period was soon to start [was hoping I was just the lucky one to get two periods back to back] and now am experiencing a twitching? Spasm? Bubbly type of feeling?
