Thump/flutter feeling in my lower left abdomen, just above my pelvic bone and intermittent headaches

My Story:

It's been a year since my dear husband and I tried to make me conceive, especially me 'coz I am already turning 32 this April.

I've had irregular periods and due to severe lumbar pains and belly bloating, I was diagnosed with PCOS.

I went to 3 different OBs as I am not satisfied with all of them. It's like they only make me pull my wallet for every consultation. So I decided to just wait and let God do His masterpiece.

Months passed and I was days late last December 19, so I took an HPT (Home pregnancy test) and I got a fainted purple line after 5 mins or longer. But on the same day, I spotted and got light to medium bleeding (I totally couldn't differentiate which is medium to heavy since I'm irregular) that took 6 days. So I assume it was a false pregnancy because I got a big fat negative repeating an HPT.

I spotted/bled lightly last 2nd week of January for 4 days and another 4 days at the 4th week of the same month. And this month, it took me 9 days of spotting, bleeding and spotting after heart's day. I had TVU (Transvaginal Ultrasound) done on the 6th day and got a negative result with retroverted and NORMAL ovaries?! Totally different from my last year's diagnosis!

And now I am confused. I've had all the symptoms a prego are having. I've been reading your threads and though I don't have symptoms like severe nausea, breast soreness and darkening nipples, I felt other symptoms like:

~acid reflux

~dizziness/faint-like feeling

~gassy feeling/flatulence

~diarrhea/lbm

~lumbar pain/sciatica

~leg pain/cramps

~abdominal cramps

~thumping/fluttering on lower left & sometimes it shifts to the right when I toss to the right

~palpitatio/breathlessnes

~headaches

~getting a hard time sleeping (I could only stay up 'til 10pm before)

~overfatigued even doing nothing

~sleepy head

~feels hot even when other feels cold

~yellow discharges

~not so frequent trips to the comfort room

All of these during the 1st trimester (based on my 1st HPT, I think I'm 13 weeks 4 days)

~I almost forgot the ligament pains in my stomach, like it feels being stretched out and bruise-like feeling when touched.

Itchy labia and not feeling pregnant since last week. Yet I still have that thump/flutter feeling in my lower left abdomen, just above my pelvic bone and intermittent headaches. Oh, I still have those gases coming out.

I just want to know if I have the same experience with anybody else. Or am I going crazy? If I'm not pregnant, why is my body acting sickly? And if I am preggy, where's my baby
