I lost 1 pill in my third week on my first pack, this is the first time being on the pill after I got pregnant with the IUD. Wondering since I lost 1 pill and never doubled up and then had unprotected sex a week later what are the chances of getting pregnant? and I forget to take the pill at the same time everyday sometimes hours later. My period only spotted 1 day on my week of and my period are very regular and normally heavy and last the full week even while I was on the IUD. I think I took a test to soon since its not even a week since I had unprotected sex.
