TWINS?? or just high HCG levels?

Zion

Got my BFP two days ago, we weren't trying but we weren't preventing - just letting nature do it's thing And we're having a babyyy🥰🥳 I'm so happy.

Only thing confuses me is that my period started 3weeks and 5days ago but the test says I'm 3weeks+ ..... Either really strong HCG levels, really early ovulation or twins right??

Edit, im now 9weeks in and it's confirmed twins
