Hi Bex
I had exactly the same happen to me last week. My breasts stopped tingling and I didn't feel exhausted, like I did the previous week. I went to my nurse to get my pregnancy confirmed and the test was only a faint positive, I was sure I was going to loss it. But over the weekend my symtoms have come back, and I even feeling a little nausious (i dont usually get morning sickness)
I've bought some 25 mIU/mL pregnancy tests of eBay, and the positive line is now darker, so my hgc levels must be rising.
I'm also 5 weeks and 5 days pregnant.
Hope everything goes ok for you.
I found this on the net, about hcg levels, hope its helpfull:
Guideline to hCG levels during pregnancy:
hCG levels in weeks from LMP (gestational age)* :
3 weeks LMP: 5 - 50 mIU/ml
4 weeks LMP: 5 - 426 mIU/ml
5 weeks LMP: 18 - 7,340 mIU/ml
6 weeks LMP: 1,080 - 56,500 mIU/ml
7 - 8 weeks LMP: 7, 650 - 229,000 mIU/ml
9 - 12 weeks LMP: 25,700 - 288,000 mIU/ml
13 - 16 weeks LMP: 13,300 - 254,000 mIU/ml
17 - 24 weeks LMP: 4,060 - 165,400 mIU/ml
25 - 40 weeks LMP: 3,640 - 117,000 mIU/ml
Non-pregnant females: <5.0 mIU/ml
Postmenopausal: <9.5 mIU/ml
* These numbers are just a GUIDELINE-- every womans level of hCG can rise differently. It is not necessarily the level that matters but rather the change in the level.
