Pregnant?

So I sent an email to Becky already but I wanted to know what others had to say:
So I dated this one guy and we were together for 10 months (Longest relationship I’ve ever had) And when I came back from china last year in July I went to his friends party (it was small no more than 7 people) and I ended up getting drunk due to jet lag ( I normally know my limit and when to stop) needless to say I lost it that night… That I started the pill in August and I stopped it in October when we broke up, also in October I had a pap smear and I got tested for stds just in case.
Everything was healthy and fine so I wasn’t worried. After we broke up I wanted to get over him as soon as I could and so I had 3 FWB one always used protection, one I never realized didn’t (though he would always pull out) and the last one after a week we started dating and I cut things off with the other two. This was in December. I also re-took up smoking in October and I’d have the occasional drink.
After December my then bf stopped using condoms and I became pregnant I didn’t notice though because my doctor said that my periods wouldn’t be regular after stopping the pill, so I kept smoking. I miscarried that February and two months later he and I broke up…
I decided in April that I wanted to come back to China and then in May I grew closer with my most recent ex’s family… I started staying over at his sisters or his younger brothers (they didn’t live with their mom) I was still smoking and occasionally having a drink and my periods were fairly regular, I knew to expect them around the beginning of every month, and that was generally a few days after I ovulated which varied from cycle to cycle.
During the month of June my recent ex’s brother and I had grown so close (they are half brothers just going t o put that out there and I’ve known him for longer than I’ve known his brother) that we decided to start dating, despite the fact that I was going to China.
The first week of June I had my graduation and he and I got drunk and had sex for the first time together, after that we consummated 12 more times (I figured it out earlier this month) and all unprotected…
This month I missed my period I’ve been having more headaches, food aversions and cravings, lower backaches, cramping, bloating, sore heavy tingly and sensitive breasts, I’ve been far more moody than I should be, I’ve been gassy, and I’ve been needing more water than I’m used to…
First off I’ve been in China for 4 weeks now, the temperature is warmer than what I’m used to, I’m over my jet lag, and I’ve told my father that I might be pregnant…
With the food thing I used to try to avoid spice but now I feel the need to add spice to all of my meals, I all but vomit when I eat oatmeal (I used to eat it no problem) I used to always fry my food because it was really simple and I liked it, not I can’t stand it. I always want fruit (the more the better) I don’t really like sour and I used to eat lemons like oranges. I don’t really like bacon, but now I can’t get enough of it!
I took 5 tests and they all came back negative, the last one I took was on the 18th of June, I also have hormonal problems, and I’ve been having ovarian cysts since I was about 13-14 years old with every period, so if I have a cyst now this is the first time without my period…
I calculated on a few different websites when I should be able to test and some told me I tested too early whereas other tell me I should be able to tell right now…
Though I’m also in China and I don’t know where to get really sensitive tests other than online (which you need a credit card for…)
I’m seeing a doctor in Shanghai on the 28th or the 30th of June and I’m asking for a blood test, a urine test, and an ultrasound to figure out what is going on…
Does anyone know what could be happening? Or does anyone know someone going through something similar? Sorry that it’s so long I just wanted to give all the background info that I could…
Thank you for any help! ^.^
ps. If I am pregnant I am keeping the baby, my family is behind me 100%, so is baby daddy I’ve told him that I could be and he says he wants to be there for the whole thing… I’m also taking a prenatal vitamin everyday just in case I’ve stopped smoking and drinking and I have been doing everything in my power to make sure that if I am that baby is healthy and safe.
Thanks again for any advice! 🙂
the first picture is my stomach relaxed, the other one is me flexing, and the last one is me pushing out (when I push out I have to pee and when I flex I have to pee and I feel sick to my stomach, not normal for me)
