TTC #2: Bloating

Erin
Hey there! I'm 35 and ttc #2. #1 is 3 and a half. I'm in the tww and am having CRAZY bloating! Like I look 4 months pregnant by the end of the day. Has anyone experienced this type of bloating before AF was due (one week before) and it was bc they were pregnant? I've been getting more and more bloated since ovulation and I usually stay pretty slim until AF arrives.
