Positive opk and period!

Linzie • ICSI in Aug 2017 BFP - 12/9/17 - MC at 6 weeks 🌈 FET - 14/12/17 Baby Girl Murren born 1/9/18 💕
I finished my last period on the 2nd of January. So started my opk on the 3rd had a blank face right through till the 9th. Took opk on Sunday 10th AM and I had a blinking smiley (high) display but started bleeding in the PM! Still bleeding heavy and this guy is still blinking smiley today!? 
Can you ovulate during a period and is it normal to have 2 periods so close to each other a week apart?
