Advice please 4dpo

Anna
Hi im looking for a bit of advice I'm only 4dpo but I'm experiencing some possible pregnancy symptoms or maybe just normal. Between yesterday and today I have been constantly going to the toilet, the past 2 nights I've woke up early hours of the morning to go to the toilet which I haven't done that in years, normally I'm a heavy sleeper and can hold it till the morning, I'm getting minor cramps, very bloated, feeling nauseous at times but for the most part I just want to eat everything in sight, don't want to get my hopes up as we have been ttc for 3 years now without success. Just wondered if these may be signs. All advice welcome. Thanks in advance
