Uncertain

Hello everyone,

I am usually 28 days in cycle.

I had my iud taken out in February (7th) to be exact, I started the pill prior to this.. about the 14th of January. I stopped taking the pill about April 28th, but because I had the IUD for two years, then went to the pill, I haven't had a period, once I stopped taking the pill on May 1st I had light bleeding.. it was brown and literally was only a little bit and wasn't multiple days.

Fiancee and I decided we were going to TTC.

Should I consider that a period?

Can you be more or less fertile after getting off the pill?

I don't know when my ovulation day is, we've been having unprotected sex for two weeks.

When should I test just in case?

So many questions, no answers.. any information will do.. Thank you in advance!
