So i’m on norethindrone birth control and i’ve been taking it since october 6th and

i’m pretty new to it. on monday i noticed some light pink spotting when i would use the restroom and then by the afternoon it was gone. well today I went to the restroom and it was more blood than what it’s been. it’s a reddish brown/ light pink color. ute not bright red like when i’m on my period either. but my boyfriend and I had sex this past saturday and we used a condom at first and then he didn’t after that but he didn’t cum inside of me. today is my ovulation day and i’ve been cranking so much but i’m also spotting. I have also been taking my birth control every single day at the right time too. I’m just still worried though. if anyone could please help or if you’re on this birth control please give me your feedback and what you’ve experienced.
