Did I miscalculate?

Hello!

I recently stopped taking birth control because my OBGYN closed permanently without any notice to me (🙄) so I ran out of pills. I got a new pack but the doctor said to wait until the Sunday after my next period.

My last period was in March. If I counted right I should’ve had my period last week (usually lands on a Thursday)

I tested this past Thursday (1 week late) in the morning and got a negative result.

I’ve been having slight cramps on and off and today (TMI….) had some brown discharge that usually continues until my period starts…. But it stopped. It’s now back to a normal clear discharge.

Do you think I ovulated later than I thought? Should I wait and test again?

I don’t want to be wasting pregnancy tests/spending more money on them unnecessarily if I don’t have to.

I have a doctors appointment in two weeks so I’m thinking I’ll let her know then if I haven’t gotten it yet.
