Hello,
Thank you for your query.
It is possible for there to be menstrual irregularities while on the pill.
Chances of
pregnancy are less than 3% while on the pill.
I recommend :
-take a home pregnancy test
- see your
OBGYN with results either way
-if positive, then you are pregnant and will need antenatal care.
-if negative,
ultrasound and blood tests to determine
hormonal imbalances may be needed.
You may also be advised a different mode of
contraception till your period regularizes.
Premenstrual symptoms can mimic pregnancy symptoms, so it would be better to check.
If you have severe bleeding or pain, see your doctor right away or go to the ER.
Hope this helps.
Please let me know if there is anything else I can help you with.
Wish you good health
