I'm 15 recently lost my virginity on the 4th of April and I'm now worrying about pregnancy. My boyfriend did not wear a condom but he also did not cum as I made him stop almost straight away from the pain of it all. My period was supposed to start on the 15th and I got it today (the 16th which is day 26 of my last cycle) however I was wondering if it wasn't my period and was instead implantation bleeding. I had terrible cramps and back ache as soon as my period started but I've had nothing since then first couple of hours and my periods been light but still red in colouring. I don't know if this me worrying over what is not necessary but any help would be highly appreciated, thanks xx
