ivf and two weeks waiting

hi dr, i had my egg pick up on 9 of october and transfer day 2 of 2 embryos 3 cell and 4 cells, i'm on cronic gel since egg pick up for two week my blood test due on 29/10 which 21 days of pick up too far hah, any way since i had pick up i feel so sick bloating crambing, tired lower back pain and feeling like 5 month pregant i mean full as this is my second ICSI first one didn't feel the same and had a child out of it, could that be due to the hormon supplement or egg pick up or implement, i know its too early to do blood test also becouse the get it could come not accuret, but i don't feel so well and as i said didn't happend before( i did transfer two embryo this time last time was just one)
