I had my period this past weekend. My period ended on sunday. I had sex friday, saturday, and sunday on my period (long distance relationship). We are currently utilizing the pull out method (i know not safe). I’m getting an iud in a few weeks. However just yesterday I started to cramp in my lower abdomen, and started to get back pains. Feels like my period but I know I shouldn’t be cramping right now, I usually don’t. Would I be feeling symptoms this early, if I was pregnant? I’ve been googling stuff to see if what I’m feeling in implantation, but would I feel implantation right now? I’m starting my fertile period today too.
