sorry your scan wasn't all it could have been mm, but try not to be despondent . I had a good HB with DD at 6 weeks, but with this baby at 6+5 there was only a teeny foetal pole. I spent the next 7 weeks till my dating scan in a state of paranoia, but all was well in the end.
Although we knew when we did the deed (Valentine's Night), the sonographer said that fertilisation might not have occured until up to five days later, and if implantation was delayed, it could make things up to 12 days out from where we had reckoned. So.....chances are that your little bean was just a bit slower off the mark
aquababe.....I found this on essential oils and pregnancy:
"Essential Oils During Pregnancy: Although opinions vary over the real dangers of some essential oils during pregnancy, most people agree that it is best to adopt a cautious approach and avoid those few oils that are considered possible risk factors. Any essential oils that is considered safe for use during pregnancy should always be diluted to half the usual strength, because the growing foetus is much more sensitive than an adult would be and also because women are much more likely to suffer dermal reactions during pregnancy than at other times. Finally, some oils, such as Clary Sage and Juniper, are emmenagogues,
which stimulate the uterus and carry a small associated risk of miscarriage. Essential oils that should be avoided in pregnancy include Ajowan, Angelica, Anise Star, Aniseed, Basil, Bay Laurel, Calamintha, Cedarwood, Celery Seed, Cinnamon leaf, Citronella, Clary Sage, Clove, Cumin, Eucalyptus, Sweet
Fennel, Hyssop, Juniper, Labdanum, Lovage, Marjoram, Myrrh, Nutmeg, Parsley, Rosewood, Snakeroot, Spanish Sage, Tarragon and White Thyme. In addition, Lavender, Peppermint, Rose and Rosemary are also best avoided during the first trimester. Parsley should not be used during menstruation"
I was told that lavender is fine, and that you would need to use it in huge quantities for it to cause any problems. considereing a lot of pregnancy creams etc have lavender in, it must be reasonably safe. If you are worried though, either don't use in the first trimester, or see if you can get advice from local herbalist/aromatherapist
