Even though Megan Fox gave birth twice in just over a year, she was soon back working in movies.

But this doesn't mean the 28 year-old actress doesn't find it difficult! In fact, Fox recently admitted that being away from her children is so hard that she may even quit acting altogether.

"I've never been an extraordinarily ambitious girl or career-oriented, but especially once I got pregnant with my first son and now [having] my second, it's so hard to be a working mom especially when your heart is not in your work, when your heart is with your family," she said to Parents magazine.

The 'Transformers' star, who is the mother of two boys, 2 month-old Bodhi, and Noah (19 months), has been married to their father Brian Austin Green, since 2010.

But Fox isn't leaving showbiz just yet, she only just starred opposite Leslie Mann and Paul Rudd in 'This Is 40' in 2012, and recently finished filming the live-action flick 'Teenage Mutant Ninja Turtles.'

However, this isn't due to her desire to be in movies, it is simply to take care of her young family financially.

"I have to make one movie a year because I have to invest in their future and I have to be able to pay their way through college and be able to provide for them," she said.

Furthermore, even when she does land a starring role, Fox makes every possible arrangement that it doesn't affect her family life too much.

"I'm looking for movies that will shoot in Los Angeles, for projects where I'm part of an ensemble so I can shoot in and out in 10-20 days," she said. "It's all about trying to spend as little time away from my kids as possible."
