I had sex on May 11 and again on the 23. I took a pregnancy test two weeks after May 11 and it came back negative. I missed my period and Ive been spotting (like two times) But my period has only been consistant for about 18 months. And I was just curious if lower Back Pain is an early sign of being pregnant?

Yes Lower Back Pain is an early symptom of pregnancy.

I had a back spasm (intense pain in my lower back) a couple days ago, but it faded after a night’s sleep. Today I’ve had this dull, minor pain in my lower back that’s just kind of there, not increasing or becoming any sort of annoyance. My urine has also been colorless, which is weird since I haven’t been drinking fluids any more than usual. Is there something wrong?

sounds like a minor problem, and not likely connected.
minor Back Pain would probably do well with an antiinflammatory like Advil. Tylenol just is good for pain.

and clear urine is actually good; means you are properly hydrated. if it is really yellow or amber, you aren’t drinking enough.

I ovulated sometime between Sunday and Monday (I got a positive ovulation test on Sunday). All day sunday and Monday, I had cramping on my left side in the abdomen area. Today I have had twinges of pain (dull) in my abdomen, and my lower back mostly on the left side hurts. Is this a sign of fertilization or something?

It could be! I swore I was having signs of fertilization at 4 days past ovulation and well I am pregnant. So, you very well may be dear!!!!

I’ve been experiencing a lot of Lower Back Pain while playing hockey. If anyone knows any exercises or stretches to help relieve it I’d appreciate it thanks!

This is for all Back Pain for the pains are a result of pinched muscles in your back. Once they are released the pain will be gone. Here is how to release them:
Back:
Place your left hand on your left knee. Place your right hand over your left shoulder and with your fingertips find the muscle next to your spine. Press on it and hold. Relax, take a deep breath and exhale and don’t tense up any part of your body. After about 30 seconds there should be a release happening and when it does slowly lower yourself forward onto your right leg. If you can lean over the outside edge of your leg it will be better for your release. Continue holding for a total of one minute. Then release but rest your body there for one minute longer. Then reverse and do the right side.
