My period and ruptured ovarian cyst occurred at the same time . how soon can i try to get pregnant if still bleeding ?

No reason to wait: Ruptured ovarian cysts are common and really do not impact the ability to get pregnant - unless you have a condition called polycystic ovarian syndrome, in which fertility is a huge problem. In general if things are going well, the most likely time to get pregnant is about 2 weeks before your period which is when ovulation most commonly happens. Bleeding from the cyst may confuse timing.
