How likely is it for me to be possibly pregnant if I am on LoLoestrin Fe and I throw up an hour after taking the pill and have unprotected sex a day or 2 later? I am continuing to take the pills and still am having sex but my boyfriend puts on a condom before he finishes. I am experiencing cramping and breast tenderness and my period is due to come next week at the end of my pill pack. I'm really nervous about this. Saw my gyn doc today and she did a urine pregnancy test and there wasn't a result for some reason so they did a blood test and I won't get the results till tomorrow or later. How likely is it for me to be possibly pregnant? I take my pill on time not a minute late every day
