Me and my boyfriend had sex on the 27th. I stopped my birth control on my sugar pill week (period week). My last period date was the 14th. I'm now late on my period (according to this app) by now almost 4 days. I'm not sure if maybe I put the info wrong or what. I'm worried 😱

He had a condom on, and ive previously had a child before. I wasn't able to get a positive test til 6 weeks with him and I took a test tonight but it was negative (I also mightve fucked it up 🤦🏼)
