Have a question. Maybe you can help me.

I had mt period on april 17, and Me and my hubby decided to TTC. I stopped taking the birth control after taking only for 1 weed.. After that, I had another perios 10 days lates and today again. Is it normal? I don't know how to track ovularions dates now. Did that ever happen to any of you? I'm worried I might have a problem or something. Thank you!!
