pull out method?? could i be pregnant?

my partner and i BD’ed during the first week of dec because we thought i had ovulated , but during and after BD i noticed clear white discharge? it was clear stretchy and quite abit in terms of amount and it sort of had an eggwhite consistency or looked like goo

he pulled out before he finished and we did it only twice

i had some bleeding which i thought was my period but it was about 1-2 days late from my expected start of period . and the bleeding was much lighter

took a test a week after first day of bleeding and it came back inconclusive (took a clearblue and it had evaps, some people could see a line but some people couldn’t)

took another test in jan and it came back negative (it was a digital) it said not pregnant

i heard some people have low hCGs which is why they don’t show up on tests + decidual bleeding monthly which is why their hCG doesn’t build up

i’ve had 5-6 days of bleeding monthly since BD, with clots and dark red blood

this whole time since dec i’ve been feeling nausea, gassy, loss of appetite, loss of 10kg of body weight, constipation

lately i’ve also been noticing my stomach has a bit of a bloat??? which isn’t common for me

if i were to be pregnant i would be 15-16 weeks based off LMP

i cant go to a GP unless i have a clear test and get referred (it’ll cost a bomb if i don’t)

thoughts? could i be pregnant?
