One week ago I missed the 10th pill of my birth control pills. I took the pill as soon as I remembered, about 12 hours later. 2 days after missing my pill, I had unprotected sex and I don't think my partner finished in me, but I'm not 100% sure. Starting the day after having sex and continuing until now, 5 days later, I have had slight on and off cramping and my breasts are a little tender. Could these just be side effects of taking a pill late, or could I be pregnant? Is it even possible to have pregnancy symptoms that early? I have taken pills late before, around one late pill once every other month, and I usually have some spotting and cramping, but this time I haven't had any spotting. I'm aware that missing one pill usually does not need a back up contraceptive, but I'm just nervous and would like a second opinion. I'm almost positive I couldn't be pregnant, but I'm freaking myself out which I think could also be causing the symptoms I'm experiencing. Any advice on what to do?? I am supposed to get my next period in a week and a half, should I just relax until then?
