I took first deposit shot dec 21st 2016, and didn't take 2 shot. I didn't bleed in the beginning but I started bleeding like 1 week before feb 25, 2017 n had sex all from feb 25 to mar 4. Can I become pregnant? Very concerned,,
FYI... still bleeding the whole time until march 8 I stopped

Pregnancy may be a possibility, but it can take some time for cycles to regulate after stopping injections... even having only one.

Until cycles become regular again, it will be more challenging to use them I epping track ovulation. If possible try to have sex every 2 to 3 days throughout each cycle, if trying to become pregnant.

If you aren't trying to become pregnant, don't assume it can't happen jut because cycles have not regulated. Use a reliable contraceptive if wanting to lessen chance of pregnancy.
