So I got off BC about a month ago and my boyfriend and I decided to try and start having a family. I've been on birth control for a while before I stopped and I've never had a problem with my periods or feeling bad. It didn't effect me really at all. But, my last period was November 23rd according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a>. And I took a test, a blood test and a urine test, and they both came back negative, and this was around the first week of January. I've still had some early symptoms and my period is due to start tomorrow. If it doesn't start, should I try and take another test? When I took the first ones, it could have been as early as a week after conception. So I don't know. Also, since I haven't had a period in so long, how would I know when I would be ovulating if I weren't to be?
