I been taking the pills for about 9 years and this month of December I had not taken any pills since I got tired of it. My period became almost irregular if I didn't take the pill for a day or two I will not see my period. I've been having little cramps and tender nipples and I had sex last week with my husband and he cum inside. Can I get pregnant?
