Heavy Implantation Bleeding Or Very Early AF

Hi so on the 6th-7th of this month I have very heavy bright red bleeding. My boyfriend and I are currently TTC since September of this year. I was diagnosed with PCOS and was put on Provera to help restart my period. Was taken off of it in August, had a natural period in September, October, and November. AF is currently two days late. This cycle I was taking ovulation tests I did miss some days, when I took the ovulation tests they were but getting darker. I may have ovulated on the second of this month and on that day I BD’d with my boyfriend. I have not taken a pregnancy test yet. My period comes a few days late anyways, so I want to wait until next Monday to take a pregnancy test. I have researched heavy implantation bleeding and it’s uncommon to have very heavy implantation bleeding, but it can happen and maybe I’m one of those few. But I just would like advice and experiences if any of you have had very heavy bleeding that turned out to be implantation bleeding. I also read that sometimes twins can cause heavy implantation bleeding, and fraternal twins run in my family, and I’ve been listening to conceive fraternal twin binaural beats sleep music. As I do want fraternal twins preferably one boy and one girl. As my boyfriend wants a boy and I want a girl. I apologize if this post is confusing, I have mental disabilities and I sometimes overshare. But any advice or comments is welcome. I can take all the help I can get as most of my family is against my boyfriend and I having a baby. And only few of my female friends are trying or have children of their own and I know more about pregnancy and TTC than they do, or they’re not tracking their cycles and taking ovulation tests.
