I missed my period in November,got it on the 5th of December and haven't gotten it yet this month. I have a 9 month old daughter and I'm not on birth control. What are the chances of being pregnant or how soon can I test where my hcg levels would be high enough

It appears your cycles are not regular at this point, missed nov, had Dec.

So if you have not had one in Jan, now would be a time to test.
