Could i be pregnant or could there be something else wrong?

I have always had regular periods and sometime it can come a day or two late which is normal for me.
My last what I thought were periods have all come a week early and I get a good amout of clotting when I get my period and I have had none the last 3...

periods and they have also been a lot lighter and only lasting half the time as my normal periods.
I have 3 sons and I feel like I did when I was pregnant with them but I did a pregnancy test a week and a half ago which came out negative.
I know I should get ahold of my doctor but I have been calling him for a few weeks with no responce and it's hard to go to a walk-in clinic with all 3 of my kids.
Has anyone else had this happen?

it is normal for that to happen keep trying for the doctor and if you already taken a pregnancy test do another one to make sure I dont think is anythink but just to be sure keep trying to ring the doctor xx

I was just worried because it's been the last 3 months and my periods are never early..if anything they are always late. On top of that I do have some pregnancy symptoms but they could be symptoms of a lot of other things too.
I've had headaches and I don't usually have them, backache , and my cramping for my normal periods usually put me on the couch for at least a day and I haven't been in much pain for the past few periods.
I don't know maybe I'll go grab another test tonight to see if it says anything different.

Do you mean one period came early and now it seems to have settled into a new cycle of them all being early (e.g. there is still the normal time between them there was, but they all seem to have just shifted forward a week because that first one did) or is the gap between each one decreasing? I would get another home test. Women tend to be pretty intuitive about these things, but be aware you make be worsening the problem by getting stressed- this could cause the headache and change in periods.

Get a home test and keep trying the doctor. I think it is worth hiring a babysitter for a few hours or contacting a friend/ neighbour/ relative to look after your kids for a few hours, so you can at least go to the drop in centre. You need to find out what is going on asap, so just free up a little window of time and go in to get chacked out. Good luck.

It was a week early the first time so I was calculating my next one from the date I ended up starting and then the next one was a week early again and then again.
It's like I have had them about every three weeks for the last three periods..but it is clean red blood no clotting which I normally have.
When I was pregnant with my youngest son I had some bleeding but I found out I was pregnant with him right away from a dollar store pregnancy test at that.
I bought a good one this time and I mean it was more than a week ago but it came out negative.
I will definatly be getting another test and if it does come out negative again I will be right on going to the doctors.
