6 Week Symptoms

Co

I am 6 weeks 3 days pregnant. <a href="https://glowing.com/glow-fertility-program">IVF</a> cycle. First 3 beta showed great rise. I am now awaiting a viability scan next week. Earlier this week I had nausea every time I was hungry, lots of breast pain when I took of my bra. Yesterday and today, almost no breast pain, only slight nausea and now a headache that comes and goes on one side. I know I’m looking too much into everything but just curious if anyone else had subsiding symptoms at this stage??
