Can someone please reply I have no experience about !

This is the 3rd time posting and I really hope someone can help. I miscarried at 14 weeks with my baby boy march 26th and bleed until april 5th. We started BDimg that night and have almost every night since. I have been watching my hcg levels and got a negative on the 18th. On the 20th I had brown an pink spotting jist a wipe or two. 2 days later I spotted more but I think it was from checking my cervix which has been high closed and soft. Then the 24th I took two tests an they came out positive the same day actually before I even took the test I had red blood that just seemed to come our. Not alot but enough to make me think af is coming. Now no more bleeding and thinking it was from our BDing the night before. The test are still faint positives but my body is saying im prego. Ive started bloating with tiredness tingly nipples and the stretching pinches in both pelvic areas. I dont know if this is a new pregnancy at almost 5 weeks post miscarriage but it seems weird for my body ro go inro prego mode a lil over 2 weeks later an not be pregnant.

Does anyone think they know of have experienced this and came out pregnant. I have appt for doc this friday but im worried
