please help

Mahwish
I am 12 days post et. On day 10 I did the beta hcg test and my levels came to 27.94. Doctor said it's a weak positive and I should do the test again in two days. Today on day 12, I did a hpt and it was positive. I also went for hcg test again and waiting for results.
The issue is I have been spotting since day 7 which does not seem to go. It sometimes is less and sometimes more. It has clots sometimes as well.
I don't know what to do and what to expect. I'm anxious and would love to hear any advise.
Thank you
