Period like bleeding that led to a positive test?

Wondering if anyone has bleed heavier and still ended up pregnant in that cycle? My cycle was all sorts of wonky this last month. We lost our twins when I was 26weeks pregnant almost 4 months ago and TTC again. My cycle is normally 28 days and I ovulate on CD14. This time I didn’t ovulate until CD 18 and then started my period still on CD 28. Glow was estimating that my period would start on CD 32 based on ovulation. Normally my cycle is heavy for the first day or so and then dies down a bit and lasts 4-5 days. This cycle on CD 26 I started spotting light and then started bleeding heavier on CD 28. I’m on day 3 of my cycle and stopped bleeding earlier today. Before I started bleeding, I could have sworn I was pregnant. Every time we have tried to get pregnant we have, but when I started bleeding I figured I was out for this month. Has anyone bleed heavier and still ended up pregnant??
