HCG and Twins

Lily

Hi ladies, today I got my second beta result.

1. 16dpo 642 (31days after LM)

2. 18dpo 1280 (33 days after LM)

I had <a href="https://glowing.com/glow-fertility-program">ivf</a> 2 embrio transfer and I wonder if i can have twins though the hcg is not too high. What do you think?
