Starting to have problems in my relationship

Good morning ladies!

Ive been with my boyfriend for 6months and we are now starting to have problems in our relationship... nothing was perfect in the beginning but they were not situations where it was a big disagreement now it was 2 back to back & im afraid this could damage us.. i know its all about communication and depends on both people i just don’t want to make a mistake by not letting things go or keeping things just to not have disagreements.. im trying my best.. the thing is not sure if after these disagreements I should probably give it a day & see him another day... we are not mad at each other its just that little tension there.. any tips?
