Oh my burps

So me and my bf have been ttc for a few months now but this past fertile week was the first week we did the baby dance every day. Well the past few days I have just not felt normal but I don’t want to over think it so I’ve pushed the mild cramps n twinges, tingling nipples off to pms even tho most the time I don’t get the cramps n twinges this far into my cycle so of coarse I’m trying not to over think it!! Well today I woke up at 615am it is now 9pm and I have burped so many times today I’ve lost count ( I’m not a burper lol) the only time I’ve ever burped this much is when I was pregnant with my other 2 kids! ( no out of ordinary foods or drinks). COULD this be a symptom of being prego or am I just going crazy?
