Okay so I made a post a week or so ago about this but I cant find my post so I am going to rewrite it. I went to my gynecologist about changing my birth control pills. She decided to switch me from Trinessa (Norgestimate and Ethinyl Estradiol Pill) to Lomedia (Norethindrone and Ethinyl Estradiol Pill). She wanted me to switch from Trinessa to Lomedia during the placebo week of Trinessa. I listened to her orders and did so on Sunday, September 18th. On Thursday, September 22, of that week I have unprotected sex with my boyfriend. Is pregnancy possible? I have been taking Lomedia around the same time I used to take Trinessa. Today, September 27th, I had red stringy discharge. Is this concerning? Am I pregnant?
