Need opinions please read?

I asked this about 6 hours ago and only got 3 answers. Its weird how all the troll questions get multiple answers when the real ones get 2 or 3. Anyway here is my question. I have a duaghter who is 10 months old, before I had her my periods where always screwy, would'nt have one for months at a time. After I had her they where on time with a reuglar 28 day cycle give or take a day or two, until 2 months ago. My last period while I dont know the excact day I started I do know that I had my period on the 4 th of July. I have had unprotected twice since then. For the last two days I have been feeling sick to my stomache and dont know if it could be morning sickness or just a stomache bug. So how likely is it that I am pregnant. Would it be to early to tell or even start to have morning sickness. With my last daughter I started having morning sickness when I was three weeks pregnant and was able to get a + with hpt and confirmed with blood test. This would be my 5th child and I have heard with each pregnancy that symtoms can be felt earlier each time. Yes I am married and can afford 5 kids so no fussing. So to recap my questions could I possibly be pregnant and feeling symtoms already? How likely is that? How far along would I be it I was to be pregnant? Please no answers stating go get hpt. I will do so, I just want opinions. Sorry for long questions just making sure all the detail are there. Thanks in advance.
