Hi, I need advice please ladies! My partner and I have had sex a few times last week after I've taken my mini pill late. Today I woke up and had awful cramps in my tummy and I put a heat pack on. It took about an hour for the pain to go away. My last period finished on the 25th of last month (nov) but is never regular so Im not sure if it's my period coming or implantation? I also had a tiny bit of blood when I went to the toilet yesterday. I don't remember having implantation pain with my first. So my question is how can you tell the difference and what symptoms of implantation did you get? And how soon could I do a hpt? Thank you!
