Bathing suits...

Ugh... Is all I can say... Ugh. I normally wear a tankini... But now it is to tight and the top keeps riding up... And the bottoms are snug... I have a maternity swim suit but it is huge on me... I am 11 weeks pregnant with my 3rd. I look like I was 20 weeks with my second... Should I just buy a smaller maternity suit? Ugh... To hot to not play in the water with the kids... And I don't like my clothes/swimsuit to tight... Idk just frustrated... Finally starting to get over morning sickness and want to play... Lol
