Higher HCG!

Hi ladies! I wanted to see if anyone had had a similar experience and what the outcome was! I have had three boys, and all I found out pregnancy 12dpo and 14dpo! (Two verified with ovulation test and conception dates!) Never any earlier. I’m now pregnant with #4 and I found out 9dpo!!! Very positive test. I have never had one come up so early. I also had pregnancy symptoms at 4 weeks! Which I never felt symptoms until about 8weeks! I’m wondering if this could actually mean anything!!
