4.5 WEEKS PG AND BLOOD GUSHES PLZ HELP!!!

Has anybody had a postive outcome after bleeding? Ive bled twice now.. This morning was a little gush and it looked like period thick red bloody mucous. It always has stopped bleeding after the initial gush and turned into light watery brown red and pink spotting or dark brown gooey spotting. 

I spotted brown from 3dpo til 7 dpo and than i had a swipe of red(i chalk it up to be implantation) and than rhe day i got my bfp(the day af was due) i got brown spotting and than the next morning i had my first blood patch. 3 days later this morning was the 2nd bigger gush.

Both times the bleed was the morning after fun time with dh... No penetration but plenty of o's(sorry tmi)

The day i got my bfp i started on 600 mg of oral progesterone(the night before 1st bleed)

Im scared to absolute death im losing this one too.
