Pregnant Mums who experience complications early in their pregnancy should be supervised more closely in current and future pregnancies.
If problems are experienced during the first three months, the risk of premature birth and other difficulties increases - in both that particular pregnancy and any subsequent ones.
It was also shown that a history of miscarriages was linked to future premature births.
A presentation was made at the European Society of Human Reproduction and Embryology (ESHRE) annual meeting and the analysis looked at several common complications in the first three months of pregnancy.
Bleeding in the first few weeks was associated with an increased risk of pre-eclampsia, premature delivery and over double the risk of having a low birth weight birth weight baby.
Accumulation of blood in the uterus - intrauterine haematoma - increased these risks even further.
Extreme morning sickness was associated with a three-fold risk of premature delivery and a similar risk of low birth weight.
Women who had previously been pregnant with twins but had miscarried one of the babies very early in pregnancy also had increased risks of later problems.
A history of one or more miscarriages almost doubled the risk in an ongoing pregnancy of the membrane that surrounds the baby rupturing in the womb, and increased the risk of a premature birth.
If any previous pregnancy had to be terminated for whatever reason, premature birth was a risk in subsequent pregnancies.
The leader of the study, Dr Robbert van Oppenraaij, of Erasmus MC University Medical Centre, in Holland, said the extent of any future complications was directly related to the severity or recurrence of the early problems.
"Events and complications in early pregnancy are amongst the most common complications in women during their pregnancy and can be extremely distressing for them.
Patrick O'Brien, from the Royal College of Obstetricians and Gynaecologists, said
"It notches up our level of awareness that if someone has problems in early pregnancy, especially repeated problems, maybe we should be watching these women a bit more closely."
