Is this normal??? Menopur and Busereline

I’ve done 3 days of stims and on day 18 of Busereline. I’ve just started to bloat now. My injections have started hurting, whereas I didn’t have any issues with just the Busereline. The Menopur injection is stinging when I inject the needle. Ive also started getting a tiny spot of blood - this didn’t happen when just on Busereline I’ve started bruising and feeling a little sore at the injection sites. Is this normal?

Any tip for getting through stims? I’ve got at least another 10 days to go.
