BF & First Period?!!

T

I had my son on May 8th. And bled for a week and then for two weeks just had spotting and occasionally a little blood.

I'm breastfeeding so Inknow that can throw off your period and i didn't with my first so I'm paranoid.

I had sex on Sunday the 2nd. He pulled out and all but ya know

When do you get your period after your second baby and when if you didn't for a while how did you handle pregnancy scares? Like how long before i should take a test? cos i don't want to wait till after i stop breastfeeding or start having symptoms to find out if i end up pregnant.

Birth control is not really an option I'm willing to consider right now.
