Am I pregnant

Hey so I have a quick question I was 13weeks pregnant and I ended up miscarrying 4weeks ago my boyfriend and I are planning on trying again so I didn’t go on birth control and condoms hurt me so we’ve been doing the pull out method until we get the ok from the doctors (which im seeing in 6days) we didn’t start having sex until 2/3 weeks ago, but since Sunday (6days now) I’ve been having cramping and lower back pain and it’s exactly how I felt while I was pregnant I literally can’t get comfortable in bed I’ve also had a metallic taste in my mouth which I didn’t get until 9weeks along.. is there any way I could be pregnant n if so will my baby be okay since I miscarried a month ago? I know you’re more fertile after miscarrying so maybe the pull out method barely works at that point? Im going to ask my doctor when I see her this Friday about it but I feel like I’m going insane and google isn’t much help… am I having these symptoms because I miscarried n they just came back out of no where or could I be pregnant? Would it be to early to even have cramping? Any advice is helpful
