Bleeding

Has anyone had a history of recurrent miscarriages ? I just had one in December and got pregnant again before having another cycle… we did a beta immediately. No idea how far I am other than 3-4 weeks maybe. Beta was only 11 and in 48 hours it only went up to 15 :( it was found I had low progesterone and was started on it immediately but I’m already starting to spot a lot of brown/pink occasionally. Anyone been in a similar boat and still had a good outcome? I keep taking tests since the last beta and they continue to get a little darker which makes me think HCG is still rising…. I just want a little bit of hope. This will be miscarriage #4 for me if this baby doesn’t stick
