Pregnancy blahs

i have always heard that every pregnancy is different. And I am starting to see that very same truth for myself. While I am only about 7 weeks along, there are already some pretty big differences between my first pregnancy and this one. For example I had a great first pregnancy, No morning sickness, no food aversions, nothing. This pregnancy however...I have the great pleasure of experiencing extreme bloating after every meal. I can eat like 4 little snack pickles and 10 mins later feel like I just stuffed my face at a thanksgiving dinner. Not to mention the extra stomach cramps that come with the bloating. Then with my first pregnancy I was very even tempered I never had mood swings, this one look out. How can one feel so annoyed at nothing? Yesterday I was so annoyed at nothing. Nothing happened to make me feel that way I just did. Then I felt more annoyed at myself for feeling annoyed at nothing in the first place...sigh The only thing that has stayed consistent with both pregnancies is that I do not suffer from morning sickness (thank the lord). Even with all the little annoyances that come with pregnancy, i am still grateful and excited to be blessed with this baby. Thats right baby singular..haha! There is only one sac this time. I go for another ultrasound in a couple days to see the heart beat and check for identical twins. (I dont think there will be two though).But ill keep yall updated.
