Possible twins? Levels? Symptoms?

Shyron

I have been spotting since 4dpo brown and pink . I did take clomid to conceive i have an inclination that im having twins. i have had a pulling and pinch pain in my hip areas on both sides . No sickness. But EXTREME hunger. I know they say you cant go off of your hcg levels . But 11/12 dpo there were 66.8 12/14 dpo 308 and 16/17 dpo 1748 which seems high from what i read. I just want to compare.
