Ok so I was 14 days late this month and I just started my period and normally I have a very heavy flow to begin with but this time it have been very light and this might be tmi but the blood is really dark. I am having cramps but not to the extent of what I normally have this is just the beginning of my second day so maybe it will change but I am just curious because I had unprotected sex (we used the pull out method I know it's not effective) and I have been super stressed about a lot of things so I don't know what to think. Help?!?
