So, here's the deal. I have been taking Generess Fe for two months now. I have never missed a pill and take it at exactly 6 PM every day. I came down with a UTI on the 23 and steered clear of sex for a couple of days. I heard the antibiotics cancel out BC so I tried to withstand from anything until the weekend came and it just kind of happened. All was well because we used condoms and he never came inside me but last night, he didn't have a condom on at the beginning and at one point he pulled out and a bit of clear liquid shot. I freaked for a minute so he put on a condom and then finished outside of me. The question is, should I go ahead and take plan B?
