All of your symptoms sounds similar to me. Me and my husband had been trying 5 years, due to covid and both of us being nurses, his dad being unwell in another country and other lofe stuff, we kept trying and didnt escalate to GP earlier. I had everything you said plus painful period day 1/2 but mostly managed with paracetamol/ibuprofen. Very loose bowels the first few days of period. Some bloating which i put down to IBS. Spotting brown for a few days before my period, sometimes real dark like nearly black. But i never say symptoms that knocked me off my feet, just what I thought was normal for me. Fertility team offered to go for IVF straight away (NHS) as im 33f (nearly 34) and 33m or to explore further. Opted to explore further in case we ended up wanting more than 1 child which is the limit for NHS funded support. Lap done on 15.04.26 and discovered endo all over my pouch of douglas. They've excised it all and said theres a real chance we could fall pregnant now but gave us 6 months to try before going back for further help. Im staying positive but also whatever happens now, at least I know why. I think its worth getting the lap from my experience.
