I think you're asking if it's possible to spot during the first 3 months of pregnancy...yes it is.
I spotted and found out that I had a low progesterone level. You should go to the doctor.
My grandmother had full periods during one of her pregnancies. But it's uncommon so please,
go see a doctor.
If that wasn't your question...then I'm not sure! LOL
I spotted at about 8wks. Freaked out because I had a miscarriage 2yrs ago. Then found out it was more then likely my placenta attaching itself to my uterine wall. Sometimes it causes spotting. My miscarriage I bleed, so as long as its just spotting you should be ok. I would still let your doctor know. Good luck, and congratulations! :)
