Not sure of there is a chance I'm pregnant

[EllieApril26]

Since January when I came of birth control I have had periods more often that normal with all of my cycles since then being about 13 days long. My last cycle was 16 days but on the 14 and 15 days I had a bit of spotting leading up to my period. I am currently on the 21st day of my current cycle which is quite a long cycle compared to what I have been used to recently. For the past few days I have been feeling a bit nauseous, more tired than usual and I've been peeing more often than I usually would. I took a pregnacy test this morning that was negative but I'm Not sure if I tested to early becuase although my period is late for my recent cycles, it's not late for the average person with a cycle of around 28 days
Is there any chance I could be pregnant?
If so when should I test?
Any help would be greatly appreciated

There is, if you've had sex. It could be too early.

Or the previous cycles may have been anovulatory and the nausea is simply a symptom of ovulation.

Or a huge number of other possibilities.

Most women ovulate 12-16 days before the arrival of af. If you had 16 day cycles, it may have been unlikely that you ovulated in those short cycles... not uncommon at all when first coming off birth control!!

Have you had your short cycles checked out? You need a decent length cycle in order for the womb lining to build up for the egg to implant into. If you don't have much womb lining then it isn't great conditions.

Yes there is a chance but you need to check why your cycles are so short.
