Too scared to do Kegels :(

Shell • Had our Rainbow Baby boy in Dec 2017 💙 and now trying for baby #2❤👶🏻🤗❤️
Last time I did kegel exercises on my commute home I started spotting then lost the baby. Now? With my rainbow baby even tho they say my kegels were a coincidence ... I'd rather not do them AT ALL. Will this be bad if I just don't do them? Women have been having babies forever before they told them to do these so I GOTTA be fine right? I hate all the rules I really do. It makes me more scared to screw up :/ between products / food / to take or avoid and blah blah bla bla bla. Feeling frustrated....thanks in advance gals.
