Hi guys so I missed a bc pill last Saturday and had one pink spot of blood on my undies Sunday night. I've been having bad heartburn for three days now and I've NEVER had heartburn before. Im on my last week of pills before i start my period. Just wondering if it's possible to be related to being pregnant or if I'm just having heart burn for no reason? Tuesday morning I also had an incredibly painful foot cramp (also which I never ever get). Maybe I'm being paranoid.... lol. Any insight would be appreciated!
