yes you can it's not the norm but for some like myself it may happen. i actually had a light period 4-5 months into all of my pregnancies which was attributed to having low level of hcg. all pregnancies were normal and the infants were fine but i did have bleeding while pregnant.
can you get bleeding heavier than spotting when pregnant around the time of your supposed period? . i know spotting can sometimes happen during implantation which usually occurs around the same time as the expected period but can that bleeding be heavier than just spotting and still be a viable pregnancy? i had last month's "period" lasting 5 days light flow but more than just spotting after having unprotected intercourse. this month's period is now 3 days late. also due to personal circumstances i used an ovulation kit during this current month which only returned negative results.
