Hi BB,
Congratulations on your pregnancy
You are right to be concerned about what exercises you can and can't do. I remember when I was pregnant I had been very active before hand and like you was scared that I might do some damage so stopped completely. That was a big mistake. My weight rocketed 4 1/2 stone which when your under 8st before hand is a hell of alot for your body to cope with. I wouldn't mind but my daughter was only 6lb.11. Towards the end of my pregnancy I was getting puffed out over the least thing.
I've since learnt that it is better to continue to exercise and you can do safely. This is important to help your circulation as your heart is put under strain with the excess work that is involved whilst you are pregnant. One of the most common complaints during pregnancy is varicose veins caused by poor circulation. Exercise will help combat that and make you feel much better and able to cope in the latter stages and for the birth itself.
Tennis and squash are probably not a good idea because of the simple fact that you could get hit by a ball at any time!. Also during pregnancy you release relaxant hormones which make your tendons and ligaments more pliable. This is to aid the widening of the pelvis to help carry the child and also vital for the birth. The problem is this hormone relaxes all ligaments and tendons not just those around the pelvic area. This leaves you vulnerable to twists and sprains in the ankles, knees and wrists which tennis and squash could certainly trigger. For this reason also it is best to avoid high impact aerobic or any contact sports or sports where you need to do a sudden change of direction. Also best to avoid exercise which involves too much jumping up and down. The baby is protected but your bladder isn't! Also you should avoid exercises where you lie on your back for any length of time as this restricts the blood flow to your baby.
Exercises which you can do are swimming, cycling (stationary if you prefer not to be out on the road), low impact aerobics (ie without jumping), walking. If you do join an aerobics class make sure you tell your instructor so that they can adapt the class for you or show you moves that you can do instead of others. Make sure your instructor is qualified as they will receive some training on exercise during pregnancy. Always listen to your body and slow down or take a breather if you feel its not right.
Best of luck with the pregnancy
