symptoms of pregnancy every once in a while. but i dont know

So my last period was around the 15 of last month. It didn’t seem normal. usually im not in that much pain, but i was. It was somewhat light and only lasted about 4 days. but anyways, it was about a week later that i got abdominal pains. but they weren’t totally like cramps. The part im confused about is that i went through a couple days of feeling headache and some nausea, but never to the point i really thought i was really going to be sick. That happened about every other day, for a week. So its going to be going on to a month soon that these pains really low in my abdomen, back pain, tiredness and feeling dehydrated have been going on. I also have been noticing break outs on my chest and feeling like i gained more weight, which i don’t like.. so what i was wondering is,.... is it possible to have the symptoms of pregnancy but them only occur every couple of days. because it isnt an everyday thing??? please help :?

I am experiencing somewhat of the same thing...my husband and I having been trying to have a baby for a while now. I was due to start my period on June 9. When it started it was light brown/pink . The next day it seemed normal and then by the third day it was gone. I have had a pretty consistent headache every day and ocasionally get light headed. Two pregnancy tests have come up negative. Not sure what to do....I have always been regular when it comes to my periods...every 28 days that last about 4-5 days.
