So I've been on birth control for years now and have never been sexual active. Now last Sunday I started my pills up again after I had my period and I had sex on Thursday. We used a condom but it broke. I bled alittle when it happened but I didn't think anything of it. Now it is Tuesday and I'm having slight cramps in my abdomen and I had a bit of blood on my underwear that stopped but was still alarming. Cramps are are very slight but I don't know what to think. I think it may just be nerves that I'm pregnant so please help me with this.
