A similar thing happened to me munchkin during cycle 2 after mc, I bled on and off all cycle and eventually passed a clot. Since then other than my lp, my cycles have been normal, no mid cycle spotting or bleeding. Fingers crossed that was causing the problem and you can get back on track.
Yes you are right and I'd be happy with an improved lp this cycle as at least ill feel closer to that bfp. I don't think it will happen this cycle anyway, just a feeling. We didn't a lot during the rest of the cycle . We'll see. I hope it's not too much longer, I'm so ready now. I know we all are. Xx
