I have been having lower back pain abdominal pain in the back of my legs i have never been late on my period before until now i'm 4 weeks late except when i was pregnant with my 2 kids...... I have no Heath insurance i'm 29 years old i cant say i fell pregnant im only really sleepy and its hard getting up in the morning I have took 5 pregnancy tests and the all have came out neg..... the pain comes and goes its not constant i have been reading everything on the computer but nothing seems right i doesn't hurt to go pee or to have sex this is so crazy and its making me nuts i am really scared.

There are rare cases where a woman could take a pregnancy test 8 months into a pregnancy and it would still read negative. Basically, sometimes it's just un-checkable. It's probably a 0.1% chance of occurrence, but it does happen. Congratulations, you're most likely an anomaly.

You might try a med. called Prem-rose you can find it at most stores, Wal-Mart or Sam's is where my daughter get hers. It will also help reg. your body and you wont fell pain when its that time of month.

I think you need to visit a doctor and take the helpful suggestion. It is one of the most common problem during the pregnancy. One of the keys to managing the lower back pain or neck pain is to actively engage in rehabilitation and exercise.
