I had twice in the beggining of the pregnancy, it didn't even burn or hurt.. but I have to take antibiotics 'till the end of the pregnancy, to make sure I don't have anymore.

could be a uti. a urinary tract infection. it's common when you are pregnant. just tell your OB. and if you end up going to a doctor other then your ER and they give you meds for it call your OB and make sure it's safe to take while your pregnant. I had one with my son and now being pregnant with my daughter I had one too. just don't wait too long it could get worse and become a kidney infection.

I agree with @theosmommy you could have a possible uti does it burn? or is it just little bits at a time like you have to constantly go

could I lose it

really

you could be having a bladder infection, call your doctor!

I been on here sinse 5am and everytime I see if I'm done it hurts

not really much you can do beside to make sure you empty your bladder all the way sometimes it's best by leaning forward or if it's a bedtime problem drink your fluids earlier in the day that way you can avoid it as best as possible at night. although towards the end of pregnancy it is almost inavoidable
