Desperate for Advice

Hi Gals. Looking for some advice here.

I ended BC back in October 2018. My husband and I conceived in November and experienced a miscarriage in January 2019. Cycles since ran anywhere between 29-36 days apart, which was pretty good. The last time I saw AF ended on April 10th - since then I have not seen AF again. I am presently around 20ish days late. Milky white and clear discharge are at an all-time high; I’m soaking through panties. I had soreness under my armpits and into my breasts last week like I did an intense work-out (which I did not) and have been bloated non-stop. The bloating is like that constant feeling of “fullness” in my stomach that you usually have after a good meal; even when I just woke up and nothing is in my system. Kind of like an ab workout just took place. I’m weirdly enough, always hungry! I’m definitely more tired than usual and have been experiencing some mild on and off cramps right around my bellybutton. Back on the 28th of May I had two days of VERY subtle tanish-brown tinted discharge that immediately went away and haven’t seen again since. I have taken multiple HPTs over the last few weeks, which have all resulted negative. The last test I took was on Saturday when I was 18ish days late. My husband and I are definitely TTC but not to an obsessive point that I was writing down our activity or tracking ovulation. I am going to the OBGYN next Wednesday but does anyone have any advice? Similar situations? How did they result?
