So I've been having all the pregnancy symptoms headaches, bloated belly, nausea, appetite, tenderness, backache, tired, etc.

If I were pregnant I would be 5 weeks and I've took numerous pregnancy tests which say negative, so I'm very confused about this.
I have been thinking about the doctors but would appreciate some thoughts first if anyone else had this and found out what was happening?
I recently had my AF what I thought it to be anyway but it lasted for two days? And mines usually lasts to 5 days and (not to be disgusting or TMI) it didn't smell like a period(AF)
I've looked up what it could be and all that comes up is spotting but can you even get spotting 5 weeks? I am so confused and would like opinions please!

It could be due to pregnancy, or just an off cycle. Did you try a pregnancy test recently or was it several weeks ago? Most women would have a positive result by 5 weeks if pregnant, but some may find that they need it confirmed by a blood test. Yes, you can have spotting at 5 weeks as some women will have some spotting or light bleeding early in pregnancy, most often to do with the development of the placenta and increased blood flow.

Options would be to wait until next month and see what happens when your period would be due; then test at that time if necessary, continue to try a home pregnancy test once a week until you expect your next period, or see your doctor and ask about having a blood test done. Personally, I would opt for the blood test so that I could know one way or the other.

Thank for your help/opinion.
I'll try a few more pregnancy tests in the last weeks, and if they keep coming out negative but I still have the symptoms I'll go try the blood test at the doctors.
Thanks again!

You are aware none of those are actually Pregnancy symptoms... they aren't even unique to women. Except being late for a period. THere are dozens if not hundreds or thousand of reasons that could explain those symptoms. And breast tenderness is very, very common among women when their period is due or overdue.

I can imagine the stress of a female can be quite enormous waiting for the next period.

Also, always test, first thing in the morning, with the first urine of the day for best results
