Два полоски за 78 дней до месячных и яркий тест: беременность двойней? У кого так было?

I got a positive on a digital 7/8 days before my period and today I did another test on a quick response. It was very positive. I know for sure I am pregnant and my period is supposed to arrive tomorrow. I am 3wks 6 days today. Question is, has this happened to you and what were your indicators of having twins? Just curious. #myfirstpost
