Need some opinions super fast!

Hey there! I'm new to this, literally only just signed up but I am going completely crazy reading posts from others which are similar to my current situation. This is gonna be a long one, brace yourselves! (I'm 21yrs old btw).

I came off the pill a few months ago, say about 4 months ago (I usually have 3 months being on the pill & then come off it so my body can regulate itself with periods & then go back on it for a further 3 months & so on - otherwise my periods become irregular & it messes my little head up)

So my early on this year me & my boyfriend (of 2 years) BD'd on 3 separate occasions - all 3 of which, nothing came of them - to my disappointment, but quite recently we BD'd again, only this time I'm sure something has came of it.

My cycle is 33 days long but I'm not completely in tune with my body so I'm not sure where in my cycle it is that I ovulate.

After countless research, website after forum after website & so on, it seems likely that I ovulated between the 26th May - 30th May, the 28th being my estimate of high fertility. Now as I say, I'm not completely sure but I'm gonna go off the 28th as my O day. The 28th was the day also that we BD'd. Also, I would like to point out that I don't chart my temp & I haven't use an OPK in a while. I'm also due on my period on the 11th June.

So this is my madness so far:

O - nothing
1dpo - ewcm
2dpo - more ewcm, nausea, diarrhoea (sorry tmi), pinching/pulling/mild cramping, temp is very warm to hot (this is unusual for me), gassy!
3dpo - watery cm, painful lower back pain - very prominent (hot water bottle to the rescue!), CP was very high (almost couldnt reach it) wet soft & open, dull cramps on & off, gassy!
4dpo - watery cm, mild cramps, pulling in lower abdomen/womb area when I stretched AM, CP was low-medium height wet soft & feels open, temp was dimming down, gassy!
5dpo - watery cm, casual mood, early morning back pain (1:37am), CP was high again - couldnt really reach it, nausea, mild cramps, gassy, banging headache - migraine like (unusual for me), sloppy stools (sorry tmi), tired - wanted to sleep but found it difficult when I went for an evening nap at 5:30pm, runny/stuffy nose (feel like a cold coming on), was intimate this day too but bf didnt ej in me
6dpo - sticky cm, bad mood, early morning crying after slight tiff with bf (3:30am), gassy, nausea, tired, wanted sex all day! snotty/stuffy/runny nose with mild sneezing, weird dreams - afternoon nap 3:30 til 6:30, stools arent fully hard yet & stomach cramps to accompany this, insomnia real bad even though I was still fatigued! Intimate again but didnt ej in me.
7dpo - dry cm, not many symptoms as previous days - extreme fatigue even after nap woke up still tired, breaking out in spots, few stomach pains, dry mouth & throat, stuffy nose with sneezing all day, little bouts of nausea throughout day, body aching like mad.
8dpo - watery cm, high body heat, post midnight cough, sneezing throughout day, stuffy nose, cramps stopped completely, (definitely feel like I have a cold), EXTREMELY tired all day, gassy!

Thats all I have upto now & I'm wondering if anyone has had the same & had a BFP or whether I can be expecting AF soon (hope the witch doesnt come). I have a 3 year old daughter & didn't know I was pregnant with her until I'd missed my period so I didnt look out for any signs or anything.

Also, I have had NO implantation bleeding to accompany any of the cramps I've had (what I assumed would be implantation) but cramps so early before AF due is really unusual for me, I usually only get cramps the day she arrives, or rarely a day before. Ive done 2 tests during these dpo which I knew would be too early if I were pregnant, both were BFN but I'm a tad obsessed with poas haha!
