Not if your
Cycle has been regular. Mid cycle bleeding is not indicative of pregnancy
because if u started on jan 2, ovulation
would be on the 16th.
Not to say u could not be, check a test, may have been pregnant longer but not from this cycle, as described. Depending on your age it makes a difference in management. If over 35 we would do an evaluation, if on the pill, that makes a difference.
