UPDATE: Please not another chemical pregnancy!!!

Got my BFP on a digital on Monday and have had BFPs on digitals and cheapies every morning since then but am so worried this might be another chemical pregnancy 😞 Am away for work this week so valled my gynae and she said I should be about 4 weeks along now (exactly what the app says - 4wks 1day today) and that I must just relax a bit and wait another 2-3 weeks before I come in for a scan if I don't get my period. She also said there is absolutely nothing I can do/take to prevent a chemical pregnancy. Has anyone had one before but done somehing differently/taken meds or supplements the next time they got a BFP and made it through the 9 months?

Update: took another digital test yesterday afternoon and got a positive (2-3 weeks) which made me sooooo happy.... and then today I started getting really bad period-like cramps near my right ovary. Have gone for a blood test, will go again in 2 days' time and just hope for the best! 🤞🏻🙏🤞🏻
