so this is my first time at trying to get pregnant. im not real sure about all the fancy terms but hopefully i get them right!

my last period started jan 28. ovulated on 16th. on the 27th-29th i had alot of discharge? on the 2nd of march i had light light brown discharge--barely noticable at all.... on the 3rd i had pink when i wiped only once though/same with on the 2nd only noticed it once. i have taken pg test only to see a neg. i did go to the doctor on the 3rd only for him to tell me it was too soon? i havnt taken a test since the 2nd it is now the 7th. i have had a misscarry before about 3 years ago but i never knew i was pregnant i only found out because i went into the er. my symptoms are basically bloated feeling my breast feel heavy and my nipples feel a bit more sensitive( i can feel them rub against my bra which normally i cant) thats started today....and gassy. those are my only symptoms if they are even symptoms.....
