It's not possible to have a period and be pregnant. A period id the shedding of the lining of your uterus and unfertilised egg if month. So therefore you cannot have this and be pregnant. Some women bleed in their pregnancy, but it;s not a period - it's just vaginal bleeding of some kind.
You can still be pregnant while having your period so just be careful it happened to my best friend she had hers all the way till she was 7 months pregnant
Not possible. Firstly because for you to be coming on your cycle means you've already ovulated and you need to be ovulating to conceive. Secondly, you cannot be pregnant and have a period too, so you're nt pregnant.
Be sure to use condoms at all times in future though to save any more scares - might not be as lucky the next time!
