Hello XXXXXXX
Your last period was on 28th Oct,am i correct?Then you had sex on 23-25th Nov and your expected date of period was around 28/29th Nov.However,your period is late?Well,if you had sex only on23-25th nov,then pregnancy chances are very less. But if you had sex earlier in that cycle,pregnancy chances are there.So if you dont get your periods after within 7-10 days then do a pregnancy test.The next step will depend on that.

If you only had sex on 23-25th nov and not any time before that after 28th oct,then chances of pregnancy are less,maybe 5-7%.Thats provided your cycles are regular and you have ovulation by day 14.

Even if you have irregular periods,if you have sex during periods,then its impossible to concieve.You may have concieved in a previous cycle followed by spotting/ bleeding.
Since you do have irregular cycles,the time of ovulation cannot be determined correctly.In normal cycles its between 12-16 day. But in prolonged cycles,it could be later.Although chances are less, 23-25th is rather late in the cycle,day 27th of your last cycle and almost rare for ovulation to occur so late.Hence, either way,pregnancy chances are low. Its too late for emergency contraception as it wont work so late.
Now,there isnt much to do but wait.If your periods dont arrive by a week,then take a test.

There is always a chance ofpregnancy however minimal it may be. But whether its topic depends can be diagnosed only by ultrasound. Take a urine pregnancy test. If its negative,no chance of pregnancy. Then your irregular cycles must be due hormonal problems. Further investigation is required.

There are many options for contraception but you are one who needs to use it. So you need to decide what to use. If you don't want to use condom then other options are available. But you need to decide when you want kids. If you don't want to get pregnancy now then you need to do something about that asap. So take a pregnancy test asap. If its negative then start using contraception now. You can either take oc pills (but you need to take them daily) or you can use a iucd. Since you don't stay with your husband iucd would be better for you so that you don't need to take pills daily. Any gyneacologist will insert it.

Since 2007, there has already there has been a long gap so another 2yrs should not pose a problem. Repeated abortions are a problem thought. Either there maybe conception problems or there may be difficulty in carrying the pregnancy. But there its any point in discussing that now since you don't want kids at present. When you decide to get pregnant then these problems can be dealt with.
