Hello there, I was on the depo shot for a year an have been for of it for a little over a month an spotted blood after the shot ran out, I recently had unprotected sex more than once, how likely is it that I have become pregnant?

It is possible, have you missed a period yet ? That will normally be the first sign, if and when you miss a period, post back for more instructions then.

My periods are irregular because of me being on the depo shot before, I had a slight period 3 weeks ago but since then had sex, I'm not sure when my next period is so I'm not sure if I missed it or not

Without knowing the period, best to wait about 4 weeks after having sex and try a urine test if you have not had a period in those 4 weeks. If result is negative, wait two more weeks and test again.

Make sure to test with first urine of the morning as soon as you wake up

Okay thank you very much!
