Help, newly p/g and having issues with my MIL. What should i do?

I am 9 weeks p/g and my husband and i are overjoyed but his mother is making my life difficult. She insists on giving advice even if i don't ask, she tells us what we should or shouldn't be doing. Keep in mind i am 28, have a college degree and have spent years around cousins, nieces,nephews and countless friends kids my whole life. I'm no expert but i'm not 16 and p/g either. I do ask my MIL for advice on occasion because i figure she can help, but lately she's becoming abrasive in how she deals with me. For example i occasionally ask questions on Y/A in the p/g and parenting sections to get advice from other mothers, my MIL now stalks me on here and any questions i ask she answers and is constantly ing in even if i don't ask her. I removed all my contacts and fans and she still went thru the p/g category and found my questions and answered them!! She also makes me feel bad if i ask a question that might even remotely pertain to her or family she gets snippy and says that she didnt mean to make me feel this way ect..ect..but she's always ing in..How can i tell her that while i love her advice if i want it i will ASK her? My own mom is super laid back and easy to confide in but my MIL is a control freak and it's driving me nuts..How can i approach this delicately?
