Pregnancy signs, period negative blood test???

Here is my story. I am 27yr old , started periods at 10, never 17 years missed a period and always regular no matter how stressed or medication I am on. had Depo injection for 6 months, on the pill for a total of about 7 years (2 & 5 years apart) period still regular and it returned on time the month that I stopped the pill. My mum has always commented on how she thought I am the type of women that would still have a period whilst pregnant, which is what I think may be happening to me right now.
Hubby & I not TTC, but been a little careless with condoms recently. I have been feeling weird sensations in my abdominal area, mostly all over (I do have IBS and used to what is 鈥榥ormal鈥?to me), but this is quite different, not in severe pain but occasional pricks, cramps in lower abd. area numb legs sometimes a bit of pain in right side, the biggest suspicious symptoms is breast tenderness which has gone on throughout this month (4-5 weeks). With these signs, I suspected pregnancy and took several HPT鈥檚 which came out negative, then finally at around 4.5 wks past unprotected sex, went to the Drs, blood test negative, had a 鈥榩eriod鈥? lighter than normal, no usual cramps). However I am still feeling pregnant. My question is, is there any link between the continued 鈥榩eriod鈥?and negative tests? Could I still be pregnant and just not producing enough HCG? If I am, I鈥檇 be about 7weeks prego. Sorry for this long post I just need someone to understand as I can鈥檛 talk to hubby, he鈥檒l think I鈥檓 a nutcase considering Doc. Says Not Prego. Help?

By the way forgot to mention stopped th pill about 8 months ago.

Here was my pregnancy symptoms.

Headaches, a very light period, lower abdominal cramping and slight sharp pains, nausea at 7 weeks pregnant until 4th month, tender breasts at 3 months pregnant, numbness in legs at 7 months pregnant when i was really big, and thats about the major ones.

By the next week you'll be 2 months pregnant i take it? For SURE your baby will be producing high enough HCG levels by now. When i was 5 weeks pregnant i already had an ultra sound and a baby was visible..small..but visible. By 7 weeks it was a size of a large bean, you need to get an ultrasound if you want to be 100% sure.

You say that you stopped your pills? Yes you do have a regular period very very regular, going off the pill can mess up your cycle because of the hormones you arent receiving any more. You MAY still might have to adjust even if you did get a period on time the month after you stopped taking it. I get my period on the 17 or 18th of everymonth for the past 7 years, i was perfect, after 3 years i stopped taking birth control, the next month i got my period on time, but the month after that i was 2 weeks late, but it once again regulated to the 18th.

well during both of my pregnancies i had 2 periods while pregnant(according to my due dates and time of conception from the dr's) so they were both very different, much lighter and i "felt" different as well so, yes you could very well be pregnant. just give it a little more time and go back to the dr or take another at home preg test in a month or so. hope that helps;)
