Can you do a pregnancy test while in your periods?
Yes you can do a pregnancy test while in your periods. But there's no need to do it because you are 100% negative. Having monthly periods means that you are not pregnant.
To know the difference, you should take a pregnancy test. If you haven't had sex for a while but are skipping periods, and you are over 35, it very well could be perimenopause or full-blown menopause. If you are sexually active, you should take a pregnancy test. It might also be early stages of menopause, but if you are still having ANY periods, there is still the chance of pregnancy.
There are a few reasons as to why you had your period for half a day and then it stopped. If your periods are just starting, it is normal for them to be irregular for a while. If you have irregular periods or are on hormonal birth control, this can also affect your periods. Lastly, if pregnancy could be possible, you should take a pregnancy test to rule that out as soon as possible.
