first time mom (update)

So we just found out I'm pregnant,most likely about a month an a half,I have a doctors appointment on the 9th in august.

ive been experiencing some cramping almost like I'm about to start my period.I don't know if this is normal or not,theyre not bad but it still worries me.

also,what symptoms should I be looking forward to. currently ive got super sore breasts that have almost tripled in size,fatigue,constipation,gas,peeing every ten minutes it seems,cold like symptoms(sneezing and runny nose),occasional headaches,ive been craving orange juice and bean burritos with extra red sauce from Taco Mayo,occasional lower back ache,I can't stand it when my husband is on top during sex or even him having his arm around my stomach its just both uncomfortable and it kinda makes me sick almost,and I cry at almost anything.

Like I said though I'm new to all this and if anything sounds unusual let me know please. and if you can lend me some advice for my pregnancy. thank you!!!

UPDATE: ive still got the cramping and I've been wearing a panty liner just in case. well anyways I noticed a light brown discharge with a little bit of white "chunks" (not sure how to explain that one but its tiny things of white discharge). is that normal?? I know you can still get your period sometimes but I don't know.
