Hi everyone, I'm new here so not really sure what I'm doing but here goes.. 

so here's my situation.. my last period was in November, nothing since (they are irregular but never usually miss one). I've done hpts throughout this month but all been negative. So yesterday I went to the toilet and noticed when I wiped I had discharge with a streak of blood in it so thought my period was coming but nothing since. I've had cramps for about a week now and also aching in my boobs which is becoming so painful!

could I be pregnant? Thanks for reading :)
