6 or 7months? Maybe. I think 28weeks is seven months. Hopefully someone else comments with a more positive answer for you! Lol.. because I'm not 100% sure on my calculations.
In my what to expect book 23 weeks is technically 6 months.
Like 5, theres a chart since each month isnt 4weeks otherwise it would be a 10month pregnancy, but i dont know it off the top of my head.
