Thanks for the query.
Menstrual bleeding anything between 1 to 7 days is considered to be normal. These variations are likely to occur due to hormonal
imbalance in the body.
Do get your pregnancy
test done as it could be implantation
bleeding as well.
If UPT is normal, then nothing to worry. You will get back your next cycle regularly.
But be careful as you may bleed a little more due to increases endometrial thickness.
Hope this helps,
