Baby is 8 weeks old... Waiting on IUD to come in (sooo Im not on bc yet). Hubby and I had sex and he pulled out buuuuut not in time 😮. I'm pumping so I think I'm okay but internet saying exclusively pumping doesn't count for BC. I haven't had a period yet. How long do I have to wait to take a test if I never had a period??
