TTC - Period/Pregnancy Q’s

My partner & I are about to start up TTC again after a BO in February. I just finished my first cycle since MC - could I get pregnant right away? I stopped bleeding 2 days ago. We got pregnant our first time trying back in November. If I did end up conceiving, would I get a positive test in 2-3 weeks around the time I would be “ovulating”, or would I have to wait until my next period was missed? My app says I’m actually supposed to ovulate from May 4th to the 10th. For my BO, I tested and got BFP early around week 3 (8 DPO). Just wondering if this would also be something like that, or if I would get BFP around the same time? Thanks for any info!! 😊
